This is a complete rework of the navigation for rotorcraft with the key features:
- all nav functions and interface in float
- nav function are registered (decoupling between nav API and implementation of standard pattern)
- submodes to specify if setpoint is a position (legacy), speed or accel (better integration of algorithms like GVF)
- guidance (H and V) is reorganized with default function to implement (run_pos, run_speed, run_accel)
- guidance control (the old default PID) is separated from the guidance logic
