It's rare with the current 5NM buffer around the origin, but if we use
the hold distance as the buffer like we maybe should it's possible for
the preferred join locations to fall entirely within the home zone. In
that case, fall back to a location within the max-turn-zone that's
outside the home zone and is nearest the IP.
This only takes effect for default loadouts. Custom loadouts set from
the UI will allow LGBs. In the default case there will not be buddy-lase
coordination so we should take iron bombs instead.
Also adds single/double Mk 83 and Mk 82 weapon data to accomodate this.
Test cases:
1. Target is not threatened.
The IP should be placed on a direct heading from the origin to the
target at the max ingress distance, or very near the origin airfield
if the airfield is closer to the target than the IP distance.
2. Unthreatened home zone, max IP between origin and target, safe
locations available for IP.
The IP should be placed in LAR at the closest point to home.
3. Unthreatened home zone, origin within LAR, safe locations available
for IP.
The IP should be placed near the origin airfield to prevent
backtracking more than needed.
4. Unthreatened home zone, origin entirely nearer the target than LAR,
safe locations available for IP.
The IP should be placed in LAR as close as possible to the origin.
5. Threatened home zone, safe locations available for IP.
The IP should be placed in LAR as close as possible to the origin.
6. No safe IP.
The IP should be placed in LAR at the point nearest the threat
boundary.
The only parts of the old weapon data that worked well (didn't commonly
result in empty pylons) did this implicitly, so make the grouping
explicit.
This also moves the data out of Python and into the resources, which
both makes the data moddable and isolates us from a huge amount of
effort and a save compat break whenever ED changes weapon names.
I didn't auto migrate the old data since the old groups were not
explict and there's no way to infer the grouping. Besides, since most of
the weapons were *not* grouped, the old data did more harm than good in
my experience. I've handled the AIM-120 and AIM-7 for now, but will get
at least all the fox 3 missiles before we ship.
This places the split point based on the best path from the IP to home,
rather than the best path from home to the target. The outcome is that
the planner might choose an alternate route out of a threatened area
based on the safest escape from the IP, which is where the aircraft
should be when it releases its weapons, rather than at the target.
That's of course not always perfect since the IP distance is not based
on the carried weapon, but it's a better choice when it matters more
(when carrying standoff weapons attacking a more dangerous target).
Try all the nav points between the origin and the target rather than
just the first non-threatened point. This prevents us from using the
fallback behavior for any target that's sufficiently far from the
package airfield.
This makes it so that the mission planning effects are applied only if
the package can be fulfilled. For example, breakthrough will be used
only if all the BAI missions were fulfilled, not if they will *attempt*
to be fulfilled.
This improves the AI behavior by choosing the stances non-randomly:
* Breakthrough will be used if the base is expected to be capturable and
the coalition outnumbers the enemy by 20%.
* Elimination will be used if the coalition has at least as many units
as the enemy.
* Defensive will be used if the coalition has at least half as many
units as the enemy.
* Retreat will be used if the coalition is significantly outnumbers.
This also exposes the option to the player.
An HTN (https://en.wikipedia.org/wiki/Hierarchical_task_network) is
similar to a decision tree, but it is able to reset to an earlier stage
if a subtask fails and tasks are able to account for the changes in
world state caused by earlier tasks.
Currently this just uses exactly the same strategy as before so we can
prove the system, but it should make it simpler to improve on task
planning.
This includes the basics that we need to get type checking for pydcs
calls.
Type checking has been disabled in a few monkey-patching cases. Patches
ought to be sent upstream (or in the case of dead unit tracking,
replaced with a better model).
This is as much as we can do until pydcs actually adds the py.typed
file. Once that's added there are a few ugly monkey patching corners
that will just need `# type: ignore` for now, but we can't pre-add those
since we have mypy warning us about superfluous ignore comments.
The loadout case actually could (and previously did) hide bugs from the
type checker, since mypy was smart enough to see that we were removing
None from the input it assumed that the member was non-optional, but
later modifications could cause null values, and since those came from
the UI mypy couldn't reason about this. This meant that mypy assumed the
type could not be optional and wouldn't check that case.

Aircraft that have no loadouts at all (such as the IL-78M) will have no
loadouts and thus no values in the dropdown menu. If the player toggles
the custom layout box we reset the flight's loadout to the selected
loadout, and with no loadouts in the combo box that is None, and
`Flight.loadout` isn't supposed to be optional.
Check for that case in the loadout selector and replace with an empty
loadout if that happens.
