Elvis33LE 6ce21609a2 raw corpus: real camera files from raw.pixls.us, oracle-tested
Seven public-domain files (raw.pixls.us), one per decode path: Canon
PowerShot SX50 HS as CR2 and as its DNG conversion, Nikon D3 uncompressed
NEF, Sony DSC-RX0 cRAW ARW, Panasonic DC-G9 high-res RW2 (10480x7794,
crop 10368x7776), Olympus E-1 with a GRBG CFA, and the Olympus E-5 as
the documented known-unsupported packed-ORF case (still previews).

xtask grows --pixls (single-file downloads, the server redirects
/data/ to /download/), a sha256-verified manifest and a --update-manifest
path; photocraft-raw gains the corpus feature and oracle tests: format,
make/model, sensor size, CFA, black/white levels and the crop are exact,
developing yields the crop in 16-bit RGB, deterministic, with sane
range coverage.

Two real findings already documented by the tests: the PowerShot CR2 and
the RX0 ARW carry no as-shot white balance we read, so the grey-world
estimate brightens those scenes (the same camera's DNG develops blacks
to ~0). Reading the Canon and Sony maker-note WB tags is the follow-up.
