JordyUSAandClaude Opus 5.5 055e95ab17 Export: FLAC (clean-room encoder; .flac files and FLAC audio in MP4/MOV) ...

New L0 crate filmcraft-flac, a FLAC encoder written from RFC 9639:
constant / verbatim / fixed / LPC subframes (Levinson-Durbin on Tukey-
windowed autocorrelation, up to order 12), partitioned Rice residuals,
left/side, side/right and mid/side stereo, CRC-8/CRC-16, STREAMINFO with
MD5 (RFC 1321, own implementation), levels 0-8, all lossless.

Export:
- Format::Flac, an audio-only .flac (16/24-bit), streamed one second at
  a time like WAV/AIFF; STREAMINFO is rewritten at the end with frame
  sizes, total samples and MD5. Preset "FLAC 48 kHz 24-bit".
- AudioCodec::Flac in MP4 and QuickTime (fLaC + dfLa), one frame per
  sample with the short last frame timed exactly; the dfLa STREAMINFO
  is replaced before the moov is written (Mp4Writer::set_sample_entry).
  MXF stays PCM.
- AudioSettings::flac_level (default 5); Export panel: FLAC (lossless)
  audio format and Compression Level; file.exportMedia `format: "flac"`,
  `audioCodec`, `flacLevel`. Spanish and Japanese strings.

ffmpeg oracle: every stream decodes bit-exactly with the STREAMINFO MD5
equal to ffmpeg's hash; .flac and FLAC-in-MP4/MOV exports decode to the
same samples as a WAV export of the range.
