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.

16-bit word and 12-bit MSB-packed uncompressed NEF, maker-note black

estimate ignoring 0xFFFF padding. Huffman-compressed NEF is reported as
unsupported (no clean-room description available).

as-shot WB from ColorBalance. Verified bit-identical to Adobe's DNG of
the same 5D Mark III frame. sRAW/mRAW reported as unsupported.
