alehel eee76c3fc2 craft-audio: AAC, ALAC, MP3, AC-3 and E-AC-3 as formats of encode and FileEncoder ...

EncodeFormat gains Aac and Alac (M4A through craft-media's MP4 muxer) and
Mp3, Ac3 and Eac3 (raw streams), so one call writes any of them from
WAV-order f32 audio and EncodeOptions.

- EncodeOptions::rate_control (with_bitrate, with_quality): a bit rate is
  moved to the nearest one the stream can carry; quality is AAC's VBR.
- Channels are mapped onto the codec's order by speaker, from
  EncodeOptions::layout. A layout the format has not is Unsupported
  instead of reaching the wrong speakers.
- M4A: the edit list skips the AAC priming, and the last sample's duration
  is cut so the track ends at the last frame written.
- encode_format_for, ENCODE_EXTENSIONS and EncodeFormat::ALL list the new
  formats; aac-encode and alac-encode now turn on craft-media's isobmff.
