Nadir camera over FPV

This feature only works on custom, experimental builds of Cyclops

You can plug the Raspberry Pi 5's J7 pins into the Matek and configure it to switch between the front facing and nadir camera views. This requires you to have the same setup from MAVLink OSD with Matek H743.

Update this parameter on the Cube Orange+:

Parameter	Value	Purpose
SR2_RC_CHAN	10	Sends RC information for VTXcamera view switching

Then update this on the matek:

Parameter	Value	Purpose
OSD_REM_CAM_CH	7	Which RCchannel to look at for the camera switching

The Pi will send analog composite video on J7, and the Matek will read the RC switched and update the displayed camera feed, C1 or C2, depending on if the switch is high or low.
