Frame 0 is always the probe; frames 1+ are always data (waveform ADC
chunks, compliance config, compliance continuation). Gating on
classify_frame() at fi>0 produces false positives: ADC binary data
can coincidentally contain b"STRT\xff\xfe", causing frames 1 and 5
to be silently dropped from the body (confirmed from live capture on
event key=01110000). Remove all type-based filtering; include every
frame unconditionally with the standard index-based skip amounts.
Add classify_frame() which categorises each A5 frame by content:
terminator — page_key == 0x0000
probe_or_strt — contains b"STRT"
metadata — contains compliance-config ASCII markers
(Project:, Client:, Standard Recording Setup, …)
waveform — binary-heavy (< 20% printable ASCII), i.e. raw ADC data
unknown — fallback
Update write_blastware_file() body loop: frame 0 (probe) is still
always processed; frames 1+ are only included when classify_frame
returns "waveform". Metadata frames (compliance config block with
Project:/Client:/etc.) and any stray STRT-bearing frames are skipped
with a warning/debug log. Terminator frame handling is unchanged.
Adds temporary print() diagnostics so each frame's classification is
visible in the server log to aid debugging.
