fix(blastware_file): never skip A5 frames based on classification at fi>0

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.
