feat(hybrid): generate Dolby Vision from the decoded video

Browse Source 
--generate-dv now takes an HDR10 base and measures L1 with FFmpeg when there is no usable HDR10+ metadata. -r HDR10 or -r HDR10P with the flag runs as a hybrid of that base alone, --sample shifts the DV RPU to match the base, and the REST API accepts generate_dv with any range.

!!! note "`generate_dv` and a hand-made HYBRID"
A service that fetches the HYBRID variants itself (HDR10 and DV) must also fetch
HDR10P when `track_request.generate_dv` is set and the title has no DV track.
The conversion needs an HEVC HDR10+ track as its base.
unshackle prefers an HEVC HDR10+ track as the base, and measures an HDR10 base from the decoded video.
`get_tracks_for_variants` does this for you.
