Download the full waveform for *event* and save it as a Blastware-
compatible .N00 / .9T0 file at *path*.
This is a convenience wrapper that calls download_waveform() (which
performs the complete SUB 5A BULK_WAVEFORM_STREAM download) and then
calls write_n00() from blastware_file.py to encode the result.
Args:
event: Event object with waveform key populated (from get_events()).
path: Destination file path. Caller should use blastware_filename()
to pick the correct .N00 / .9T0 extension.
serial: Device serial number (e.g. "BE11529") — passed to
blastware_filename() for reference, but the caller supplies
the final path.
