Dylan M. Taylor 44b4a23137 craft-audio, craft-media: the changes FilmCraft and SoundCraft made to their copies since extraction (#807) 
* craft-audio: FilmCraft's FLAC encoder and MP1/MP2 decoder speed-ups

FLAC: per-order predictor kernels, merged Rice partition sums, the LPC
window kept per block length, and batches consumed by offset
(filmcraft 5eaff794, d9dad4a5). The output is unchanged: 64 golden cases
hash the same before and after.

MP1/MP2: the faster synthesis filterbank (filmcraft 51c755e5), with its
bit-exact test.

* craft-audio: FilmCraft's AAC and Opus decoder speed-ups and refactors

AAC: table-driven Huffman decoding, per-stage FFT twiddles and fused
stages, reused per-channel work buffers, and the encoder's memoised
per-band work (filmcraft f9627280, d587ceed, 6121635c, dc124ab7,
7a532eca).

Opus: radix-2/3/4 FFT kernels in the CELT IMDCT, the PVQ table built
once, one de-emphasis loop for both channels, the SILK resampler
without per-sample divisions and with eight partial sums, concealment
and FEC capped at 120 ms (filmcraft bf7ac420, 12e32026, c4dc64d1,
eb352ec8, 87b8e22d, 014b5e56, 78d77b72).

The per-frame mid-only flag this crate fixed in the SILK decoder is
kept in the refactored decode.

* craft-media: Ogg CRC-32 by slice-by-16

FilmCraft's 6763f9bf: sixteen independent lookups per 16 input bytes, so
opening a file is several times faster. Checked against a bit-at-a-time
reference on every short length and alignment, and across every split.

* craft-audio: SoundCraft's CAF cookie-size and FLAC vendor-length checks

A CAF magic cookie size above the signed range is refused instead of
passed to symphonia (soundcraft 3bd3965), and a Vorbis comment block
whose vendor string claims more than the block holds is refused
(soundcraft ddfe991). Each with its regression test.

* craft-audio: AC-3 reads bits through the shared BitReader

FilmCraft's 1c9c2e82: the AC-3 decoder's private bit-at-a-time reader is
replaced by craft-media's BitReader, with its two tests: the decoded
output of 2,000 synthetic and 12 real syncframes (and their damaged
variants) hashes the same as before, and the reader agrees with the old
one on random reads, skips and overruns. The three AC-3 features now
turn on craft-media's bitstream module.

* craft-audio: the quantiser rounds without a libm call

SoundCraft's d293336, the audio-io part: round-half-away by integer
arithmetic in the bounce's inner loop, with its test against f64::round
over the quantiser's range.

## Assets embedded by the optional PDF writer
Krilla 0.8.2 bundles the following Compact ICC Profiles by Clinton Ingram, under CC0-1.0.
The immutable source revision is `3ffdf0588cf98050aad6edba51ca70162e1fb5b5`, recorded by the
registry package's `.cargo_vcs_info.json`. These are the same dependency profiles already
used by the apps' Krilla exporters. The local backend snapshot retains these four profiles; the optional writer adds no font binaries.
The profile licence is retained in `licenses/pdf-writer/LICENSE-ICC.txt`.

The four Krilla ICC entries above are also stored unchanged in `vendor/krilla/icc`.
The vendored source patches are in `vendor/krilla/patches`, described in `vendor/krilla/README.craft.md`; per-file hashes are in `vendor/krilla/SOURCE.json`.
## Assets retained with the optional PDF reader
The shared reader centralizes the five patched Hayro source trees from PdfCraft and the
patched crates.io `hayro-postscript` 0.1.0 scanner, which bundles no assets.
The standard-14 fonts, CMYK profile and generated metrics listed below remain byte-identical
in `vendor/hayro-interpret`, and the CMaps in `vendor/hayro-cmap/assets`; no application
document fonts are added. The removed upstream LAB.icc profile is not restored. Source hashes
and the exact transfer revision are recorded in each vendored crate's SOURCE.json.
