Some SAMs have multiple groups (such as an SA-10 group with its
accompanying SA-15 and SA-19 groups). This shows each group's threat and
detection separately on the map, and also makes it so that an SA-10 with
dead radars will no longer contribute to the threat zone just because
the shilka next to it still has a functioning radar.

Converts the landmap to use MultiPolygon instead of a collection of
polygons, since Shapely has explicit support for this.
Because we've done that, we can use a single projection from a line
instead of brute forcing the extent of the front line.
This makes turn processing ~66% faster (3 seconds to 1.8).
There are probably other places this should be used.
Started with TARCAP because they're simple, but will follow and extend
this to the other flight plans next.
This works by building navigation meshes (navmeshes) of the theater
based on the threat regions. A navmesh is created for each faction to
allow the unique pathing around each side's threats. Navmeshes are built
such that there are nav edges around threat zones to allow the planner
to pick waypoints that (slightly) route around threats before
approaching the target.
Using the navmesh, routes are found using A*. Performance appears
adequate, and could probably be improved with a cache if needed since
the small number of origin points means many flights will share portions
of their flight paths.
This adds a few visual debugging tools to the map. They're disabled by
default, but changing the local `debug` variable in `DisplayOptions` to
`True` will make them appear in the display options menu. These are:
* Display navmeshes (red and blue). Displaying either navmesh will draw
each navmesh polygon on the map view and highlight the mesh that
contains the cursor. Neighbors are indicated by a small yellow line
pointing from the center of the polygon's edge/vertext that is shared
with its neighbor toward the centroid of the zone.
* Shortest path from control point to mouse location. The first control
point for the selected faction is arbitrarily selected, and the
shortest path from that control point to the mouse cursor will be
drawn on the map.
* TARCAP plan near mouse location. A TARCAP will be planned from the
faction's first control point to the target nearest the mouse cursor.

Creates threat zones around airfields and non-trivial air defenses (it's
not worth dodging anything with a threat range under 3nm). These threat
zones can be used to aid mission planning and waypoint placement.

Not converting all at once so I can prove the concept. After that we'll
want to cover all the cases where an int distance or speed is a part of
the save game (I've done one of them here with `Flight.alt`) so further
cleanups don't break save compat.

* Introduce a real type.
* Rewrite _transform_point to make use of Point.
* Add shift modifier for large (10 pixel) adjustements to reference
points. Unmodified behavior is now single pixel.
* Use WASD for moving the second point (shift modified numpad keys don't
seem to work).
* Add a debug option to draw transformed reference points to check for
errors. If they don't overlap, something is wrong.
* Cleaned up all the existing reference points. Caucasus in particular
is now *much* better.
As an added bonus, the cleanup for carrier movement projection now also
shows an invalid destination when the destination is on land.
Ensures frontline stays outside of exclusion zones by adjusting its
position and width
Adds a DisplayOption for viewing the frontline vector on the map
Doesn't allow helos or harriers to do it either even though they should
be able to because we don't currently support ground spawns, which would
be needed to prevent those aircraft from using the runway. Even then, I
don't know if they can be forced to *land* vertically.

Breaks save compat because it adds new fields to `Flight` that have no
constant default. Removing all of our other save compat at the same
time.
Note that player flights with a divert point will have a nav point for
their actual landing point. This is because we place the divert point
last, and DCS won't let us have a land point anywhere but the final
waypoint. It would allow a LandingReFuAr point, but they're only
generated for player flights anyway so it doesn't really matter.

The AI isn't making use of these yet, but it's not smart enough to do so
anyway.
Would benefit from an icon to differentiate it on the map.
I'm stretching the definition of "control point" quite a bit. We might
want to put a class above `ControlPoint` for `AirSpawnLocation` to
represent types of spawn locations that can't be captured and don't have
ground objectives.
