`lightcraft_raw::sparse::header_plan` says which byte ranges of a raw file the header probe (`probe_info`, `lightcraft_meta::extract`) reads, given a buffer of the file's length in which only some ranges are loaded: everything but the bulk sample data (large TIFF strips/tiles minus the first chunk's coding headers, a CR3's image tracks minus the raw track's CRX headers and QP maps, a RAF's CFA strip, an RW2's raw data). `preview_plan` also reads what `embedded_preview` needs, for raws shown from their preview. NEF, ORF and PEF (their header probe looks at samples) and anything else are read whole. The corpus test checks, for every raw.pixls.us sample the plan describes, that probing the partly loaded buffer gives exactly what the whole file gives, with the skipped bytes zero and again 0xFF: CR3 2.7 %, DNG 2.4 %, CR2 3 %, RAF 6 %, RW2 7 %, ARW 8 % of their bytes.
