rxdrone support

[8858hn92dc-bit]

hello,

I see a rxdrone.md there, but i`m not sure if it is supported control the drone.
I try to set DRONE_TYPE=cooingdv_jieli . However it seems not work.

btw, i found those rxdrone rstp video stream address:
rtsp://192.168.80.1:554/264_rt/front.sd
rtsp://192.168.80.1:554/264_rt/front.hd
rtsp://192.168.80.1:554/264_rt/rear.sd
rtsp://192.168.80.1:554/264_rt/rear.hd

I started a research doc to track some of the details about the app after decompiling it, but I don't have a drone that uses the rxdrone app/package to test with just yet.

Feel free to add an experimental implementation in the meantime though, and thanks for those rtsp streams, I'll add it to the research doc.
