pub const SNIFF_PREFIX_LEN: usize = 16; // 16usizeExpand description
The probe itself, re-exported so znippy_common::precompressed::* keeps
naming exactly what it always named. These are ldeflate’s items, not copies
of them — breaking one there breaks every znippy caller, which is the point
of the move.
Bytes of prefix the probe reads. Sized by WebP, whose form type sits at
offset 8..12 — the longest anchored pattern here.
