#372: uncompressed QuickTime (raw RGB / ARGB) output module format

Browse Source 
Problem: the Render Queue had no single-file uncompressed output, so
handing a render to an external encoder meant a lossy codec, ProRes,
or an image sequence plus a separate WAV.

Fix: add the "QuickTime (Uncompressed)" Output Module format. Frames
are stored as QuickTime 'raw ' samples: 8-bit RGB (depth 24, rows
padded to even bytes) or ARGB with RGB + Alpha (depth 32), written
through FilmCraft's existing QuickTime muxer with PCM audio
(16/24-bit or float) like ProRes. Format name `uncompressed` on the
control channel; disk-space estimate and Sample Format menu included.
