Claude cf9d8f7ebb M11: name Nikon High Efficiency NEFs instead of blaming a missing table (#193) ...

High Efficiency NEFs (HE / HE★, Z 8, Z 9, Z 6III, Z f) keep compression
34713 but carry a JPEG XS-based codestream (SOC + CAP, FF10 FF50) and no
maker-note 0x0096 table. They fell through to "Nikon compressed NEF
without a linearization table", so the Preview only notice gave Z f users
no hint why their raw wasn't decoded or that Lossless compressed NEFs work.

Detect the codestream before asking for the table and report "Nikon High
Efficiency NEF" with the workaround. Add a synthetic regression test, CC0
Z f HE + Lossless samples to the corpus (raw.pixls.us) with a corpus test,
and list HE NEF among the format gaps in parity.md and ROADMAP.md.

No decoder: the format has no public specification and the existing
decoders (LibRaw, rawler) are LGPL and derived from Nikon's binaries.
