Path saving: add partition for Quanton
Path saving: add revolution support
Path saving: add support for revomini
Path saving: add support for flyingf4
Path saving: add support for FlyingF3

reserved for saving.  That means both the settings and waypoints
partitions only have two arenas each.

have static.
Path saving: add to simulation
Simulation: fix for pios_debug
