This appears to be incompatible with pyinstaller. I get the following
when trying to run the executable generated with pyside6:
```

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.

This way the results of committing the debriefing can't alter the view
of the debriefing. It looks like it was probably that case that
debriefing information displays (but not the committed results) would be
incorrect after a base capture because the results might be shown after
the results were committed.

This removes both the double load that happens on startup and also
makes it possible to get the UI to create a new game if the existing
default.liberation is not compatible.
This guarantees that we update the map *after* updating the model that
the map uses to draw flight plans. Without this, after creating a new
game we'd redraw the previous game's flight plans because the model
hadn't been updated by the time the map was.

Mission planning has been completely redone. Missions are now planned
by right clicking the target area and choosing "New package".
A package can include multiple flights for the same objective. Right
now the automatic flight planner is only fragging single-flight
packages in the same manner that it used to, but that can be improved
now.
The air tasking order (ATO) is now the left bar of the main UI. This
shows every fragged package, and the flights in the selected package.
The info bar that was previously on the left is now a smaller bar at
the bottom of the screen. The old "Mission Planning" button is now
just the "Take Off" button.
The flight plan display no longer shows enemy flight plans. That could
be re-added if needed, probably with a difficulty/cheat option.
Aircraft inventories have been disassociated from the Planner class.
Aircraft inventories are now stored globally in the Game object.
Save games made prior to this update will not be compatible do to the
changes in how aircraft inventories and planned flights are stored.
