Use stacking algorithm in "_generate_over_departure"

Resolves #57

"_generate_over_departure" is the method used to generate flights in the air when no more parking spots are available. Pydcs changes were required as it turned out aircraft were trying to spawn on helicopter parking spots, which forces them to start in the air by DCS itself.
