Jason Baldwin 7883333420 LR-IMP-CAMERA-COVERAGE: Sony ILCE-7CM2 ARW codings in the corpus (#697)
Issue #697 (ILCE-7CM2 lossless compressed M-size ARW "washed out" in 0.4
and 0.5) is the 512-vs-1024 YCbCr pedestal of #535 item 3, fixed on main
by 3100cc1a after v0.5.0. Measured on the reporter's file: 0.5.0 renders
the darkest half of the dusk scene +11 L* and blue against the camera
JPEG, with the lamplight turned white (mean dE 11.8); main is within
+3 L* (dE 8.9). Its darkest 0.1 % per channel sits at 1017/1020/1024,
confirming the 1024 pedestal on a fifth body.

- Corpus: two CC0 raw.pixls.us ILCE-7CM2 files, lossless L and the
  compressed "M-size" coding, which is Bayer at 4736x3132 with black 512
  (only the lossless M/S codings are YCbCr), so a size-based pedestal
  rule would break it.
- Tests: corpus_sony_a7cm2_codings (model, layout, levels, crop, as-shot
  gains, header/full agreement) and both files in the #535 data-floor
  test.
- docs/parity.md: the ILCE-7CM2 verification on the Sony coverage row.
