Route emergency stop, arming and crash recovery through the supervisor

crazyflie-lib 0.8.1 moved these commands to the new supervisor
subsystem and deprecated the localization and platform methods, which
fails our build under -D warnings. Call the supervisor methods
internally instead; the Python API is unchanged and keeps exposing
them in their current locations.

Moving them under a supervisor subsystem in the Python API too is left
to the pending supervisor subsystem PR.
