The Pi 4B is now able to register the camera and its HDMI output settings such as resolution and frame rate.

This is the Air Unit. I also need to configure the Ground Unit, though it should be a similar process except the Ground Unit does not input any camera signal, so that makes it a bit easier. They both use the same packages like `WFB-NG`, `rtl88xxau_wfb` driver, `GStreamer`, etc. #drone
