[rt_paparazzi] Update 0.1.2
- Thread definitions moved into proper subsytems files
- No MACRO for thread defines
- IMU GX3 subsystem, AHRS and IMU subsystems connected in more general way (callbacks)
- new AggieNav AHRS (as a proof of concept, right now it only rotates the attitude data from IMU)
- telemetry fix for IMU GX3 in ChibiOS
