Radar controller returning reference

Out:

Passing a reference to "Tracker" ensures the tracker does not have its own copy of the radar

tcontroller.radar.tx.pointing: [2.24951054e-01 1.37742794e-17 9.74370065e-01]


setting "return_copy" to false makes the returned radar from the controller as just a reference
