Transaction Science 8449619b65 tonemap: the corpus's second implementation, and two binding controls ...

tonemap_verify.py, written from extensions/exact-tonemap.md: its own integer
log2/exp2, sRGB table, gain map and ST 2094-50 derivations, Annex C reader,
PCHIP on exact rationals and PNG reader; envelopes and SPEC §7.1's component
rules through staged_verify.py, which now knows the two new companions' base
classes. It agrees with wai-rs on every case, recomputes §6's measurement,
and catches every mutation and every dropped check. Two cases added so the
binding check is load-bearing: a base index that names the companion, and a
gain map bound by id to another rendition than the record's base.
