Open‑source VANTRUE dashcam stitcher (front and cabin PiP)

I vibed together a small script to stitch VANTRUE front + cabin clips into a single picture‑in‑picture video.

It groups sessions, supports date/week/month filtering, and uses FFmpeg. There’s also a cleanup helper for moving/ deleting processed originals.

Happy to take feedback or feature requests (rear camera _C.MP4 support planned).
