- move to ModuleBase
- strip down to PWM 8 and 16 modes only
- remove all dead code
- implement missing pwm ioctls (current value, rates, etc)
- default rate 50Hz -> 400Hz
The main changes include:
* Better attitude tuning for airframes (more realistic models, the models had previously not as much thrust as the real vehicles)
* Better waypoint and navigation default parameters which match the on-hardware parameters
* More suitable minimum and trim airspeeds for VTOL and fixed wing which prevents stalls that happened in SITL previously (the new airspeeds match the real vehicles nicely)
