Axial: mapping and controlling the DJI RS 4 Mini over Bluetooth

Axial documents and implements Bluetooth control of the DJI RS 4 Mini gimbal. Its Mac GimbalProfiler observes messages and tests commands, while an iPhone app uses a model-specific .axial profile and shared DUML framing to send controls and decode signals.
