annotate_blastware_binary(raw) → a gap-free tiling of labelled Spans
(header / STRT / per-channel sample records / footer / unknown) for a hex
viewer to paint. Every byte is covered; anything the decoder can't account
for is a first-class `unknown` span, so undecoded regions stand out.
Composes the existing waveform_codec.walk_records over the body between the
STRT record and the 26-byte footer. On the cracking fixtures this already
surfaces a ~1700-byte undecoded trailing region (stream-end marker + serial +
…) per file — a candidate home for stored spectral/FFT data.
TDD: tests assert the spans tile the whole file, STRT is located, the geo
sample records are labelled, and the footer is last.
