The previous method of using a uniform scalar of the MSL wind speed for
higher altitudes didn't offer enough control. In particular, the shape
needs to be quite different to skew low, mid, high.
This patch reworks that system so the parameters of each distribution
are configured per-altitude level. To keep some continuity between
altitudes (on a windy day, all levels should have higher wind speeds on
average), the wind speed of the lower altitude will be added to the
scale value of the higher altitude.
Since it wasn't practical to approximate the previous behavior with the
new system, this also handles the tuning of each. The low altitude
speeds remain mostly unchanged (typically around 5 knots expect for
thunderstorms), but the average speeds for other altitudes went up to
more closely match the previous intent but without the massive
overshoot. At 2000m wind speeds are typically in the 20-25 knot range
now, and 8000m 30-50 knots.
https://www.quora.com/What-is-the-average-wind-speed-at-different-altitudes
has some of the source data, and Quora is the most authoritative source
there is. It claims that cruise altitude winds can get "as high as 150
knots", but doesn't claim anything about the average. I had a
surprisingly difficult time finding good data for cruise altitude air
speeds for non-jet stream paths (though many of our maps are in jet
streams), so I just eyeballed it from
https://turbli.com/wind-during-flights/.

Wind speeds should not be uniformly distributed. This switches to a
Weibull distribution which allegedly (see the bug) is good enough.
Experimentally that seems true as well, though I know nothing about how
wind works irl. This at least looks like it'll generate reasonable
variation in missions while keeping the 1st through 3rd quartile
behaviors from getting out of hand.
I'm very uncertain about the scaling factor aspect of this. Naively the
wind speeds at different altitudes ought to be somewhat correlated, but
I'm not sure how much, and whether this kind of scaling is at all the
right way to do it. As before, meh, close enough?

We want other pieces of country information (in particular the short
names). This cleans up a lot of code anyway.
As an added bonus, this now catches squadrons that used invalid names
which would previously be passed through to pydcs and... then I don't
know what would happen.
We're still using mostly the same aircraft selection as we have before
we added squadrons: the closest aircraft is the best choice.
This adds an option to obey the primary task set by the campaign
designer (can be overridden by players), even if the squadron is farther
away than one that is capable of it as a secondary task.
I don't expect this option to live very long. I'm making it optional for
now to give people a chance to test it, but it'll either replace the old
selection strategy or will be removed.
Fixes https://github.com/dcs-liberation/dcs_liberation/issues/1892.
After this change, players will always have the final say in what
missions a squadron can be assigned to. Squadrons are not able to
influence the default auto-assignable missions either because that
property is always overridden by the campaign's air wing configuration
(the primary and secondary task properties). The `mission-types` field
of the squadron definition has been removed since it is no longer
capable of influencing anything. I haven't bothered cleaning up the now
useless data in all the existing squadrons though.
Fixes https://github.com/dcs-liberation/dcs_liberation/issues/2785.
Preferred aircraft per task are now determined by a ranking of weights
stored in the aircraft yaml files. To aid in visualizing the priorities
across aircraft, Liberation can be run with the argument
dump-task-priorities to dump a yaml file in Saved
Games/DCS/Liberation/Debug/priorities.yaml, which will show each task
along with priority sorted aircraft and their weights.
The current weights in the data were exported from the existing lists,
where each position from the bottom of the list was worth 10 (to allow
some games for less shuffling later).

The collections are copied by reference into the descendants, whereas
_loaded is copied by value, so that one can stay. Before this patch,
every subtype was loading because _loaded was set per subclass, but they
were all registering with a common collection defined by UnitType rather
than their own class.

The mechanism for how this bug arises is that the *WaypointGenerator*
uses the *FlightWaypoint.waypoint_type* to decide whether to generate
the waypoint in the .miz file using a *DeadIngressBuilder* or a
*SeadIngressBuilder*. This *waypoint_type* is set by
*ato.flightplans.<sead|dead>.Builder*, which is set when *ato.flight* is
initialised in the *Flight._flight_plan_builder* member variable based
on *Flight.flight_type*. When *Flight.flight_type* is updated when the
flight is changed from SEAD->DEAD, *Flight._flight_plan_builder* is not
updated in the development build, resulting in it continuing to generate
SEAD waypoints.
This PR adds *set_flight_type()* which sets the *flight_type* property
and updates *Flight._flight_plan_builder* and uses this function when
converting flight types. Ideally, *flight_type* should be made private
and only accessed through getter/setter functions that encapsulate this
behavior, but that would mess up any existing liberation save files.
This PR was tested by:
1. Opening the save file from Issue 2779 in the development build
2. Clicking "Take Off" and confirming that the Weapon Release Type is
"Guided" at the Ingress Waypoint as described in the issue.
3. Opening the save file from Issue 2779 in this PR
4. Converting the SEAD2DEAD flight from DEAD back to SEAD, and then from
SEAD to DEAD
5. Clicking "Take Off" and confirming in the mission editor that the
SEAD2DEAD flight has Weapon Release Type set to "Auto" at the Ingress
Waypoint.

We've actually been pretty good at getting this right in most of the
code base, but we've missed it in a few places. Python defaults to the
encoding of the current locale unless otherwise specified, and for a US
English Windows install that's cp1252, not UTF-8. I'm not brave enough
to change the locale at startup because I don't know how that might
affect CJK encoding users (or for that matter, non-Latin derived
alphabet UTF-8 variants).

Probably the final Fix#97
Unused aircraft (assigned upon takeoff) would get claimed but since it's not possible to delete those flights after aborting, these flights wouldn't get released anymore. This should fix that issue, including a migrator change to correct the number of claimed aircraft per squadron.
