Brian Harrison 9bf20803c2 feat: fetch event-time metadata from SUB 5A bulk waveform stream ...

Add read_bulk_waveform_stream() to MiniMateProtocol and wire it into
get_events() so each event gets authoritative client/operator/sensor_location
from the A5 frames recorded at event-time, not the current compliance config.

- framing.py: bulk_waveform_params() and bulk_waveform_term_params() helpers
  (probe/chunk params and termination params for SUB 5A, confirmed from
  1-2-26 BW TX capture)
- protocol.py: read_bulk_waveform_stream(key4, stop_after_metadata=True) —
  probe + chunk loop (counter += 0x0400), early stop when b"Project:" found
  (A5[7] of 9), then sends termination at offset=0x005A
- client.py: _decode_a5_metadata_into() needle-searches concatenated A5 frame
  data for Project/Client/User Name/Seis Loc/Extended Notes; get_events() now
  calls SUB 5A after each SUB 0C, overwriting project_info with event-time values
