Brandon ThomasandClaude Opus 5.5 1813bbaca2 M9.7: AV1 headers, symbol decoder, CDFs, intra decoding, transforms, intra prediction ...

New L0 crate filmcraft-av1 from the AV1 Bitstream & Decoding Process
Specification v1.0.0 with Errata 1 (tables extracted from the spec's Markdown
source by tools/extract_tables.py).

Stages: OBU parsing, sequence and uncompressed frame headers (all fields),
reference state (set_frame_refs, load_previous, reference update,
show_existing_frame), symbol decoder with CDF adaptation and
init/load/save/frame-end CDF handling, tiles, intra frame mode info
(partitions, segment ids, delta q/lf, CDEF index, modes, angle deltas, CfL,
palette, filter intra, tx size), coefficient decoding, dequantisation,
inverse transforms (DCT 4-64, ADST, identity, WHT), intra prediction (all
modes, edge filter/upsampling, recursive filter, CfL, palette), LR syntax.

All-intra libsvtav1 streams with in-loop filters disabled decode bit-exactly
against libdav1d (8/10-bit, 128x128..1280x720, odd sizes, presets 2-8).
