jl-dv-viewer: reconstructing Jieli-DV camera streaming

jl-dv-viewer reconstructs the local streaming exchange of Jieli-DV-style Wi-Fi rearview and dash cameras in a Kotlin Android viewer. It sends length-prefixed CTP control messages over TCP, reassembles custom UDP chunks into MJPEG frames, and documents the command vocabulary and frame format. The app also offers crop, rotation and reconnection controls.
