Sweep: crop the timecode band off published streams (re-encode after decode); vgdeband.sh catch-up

The published recording is the game picture + audio + tmcd track, nothing else. Streams without the
band are still remuxed losslessly. vgstrip plan exports TC_BAND and marks the sidecar band_removed.
