LoRa based inter UAV communication

INAV-Radar is an addition to the INAV flight control software, it relays information about UAVs in the area to the flight controller for display on the OSD. INAV-Radar does this by using LoRa radio to broadcast position, altitude, speed and plane name. It also listens for other UAVs so INAV OSD can display this information as a HUD.
