- embedded_preview: CR3 PRVW/THMB boxes (plus RAF, RW2, ORF, PEF from the
format commits); stops at the first valid box of each kind
- engine: raw variants that report Unsupported are probed and shown from
their embedded JPEG (orientation from the JPEG or the raw), not an error
- crates/raw/tests/corpus.rs: every corpus/raw file is recognised, has a
JPEG preview (DNG optional) and decodes or is a known-unsupported
variant; prints decode timings
- xtask corpus --download: 37 CC0 raw.pixls.us samples (matched by SHA-256)
- ROADMAP/crate docs: format coverage, NEF Huffman / RW2 format 4 /
compressed ORF+RAF gaps, neutral colour-matrix fallback

16-bit LE words (12-bit-in-top-bits detected and shifted), 12-bit rows
of LE 32-bit words read MSB-first (black-box), maker-note
ImageProcessing crop, BlackLevel2, WB_RBLevels for old- and new-style
notes, CFA phase from the data (GRBG/RGGB), CameraSettings preview.
Compressed ORF reports Unsupported (documented gap).

Black-box derived layout: 0x4000-byte chunks stored rotated by 0x1ff8,
16-byte LE blocks read LSB-first (10x12-bit or 9x14-bit samples).
Sensor borders, CFA code, per-channel black, linearity limit, WB levels,
ISO; JpgFromRaw preview via a generic undefined-tag JPEG candidate.
The quantised raw format 4 reports Unsupported (documented gap).
Adds a rawdump debug example.

RAF header/record parsing, raw IFD (0xf000) with 16-bit, 12-bit LSB and
32-bit-word MSB packings found by black-box analysis of CC0 samples,
X-Trans layout (reversed record, anchored at 0,0), crop, black levels,
WB_GRB levels, metadata and preview from the embedded JPEG. Compressed
RAF reports Unsupported. Colour uses the documented neutral fallback.
