Listens for inbound unit connections, connects upstream to a real Blastware
ACH server, and forwards bytes bidirectionally while saving both directions to
raw_bw_<ts>.bin and raw_s3_<ts>.bin in the existing capture format.
Used to capture the 4-11-26 Blastware ACH session that confirmed the erase-all
protocol (SUBs 0xA3/0x1C/0x06/0xA2) and the event deletion wire sequence.
Usage:
python bridges/ach_mitm.py --bw-host 127.0.0.1 --bw-port 9999 --listen-port 9998
Point the unit's call-home destination at this machine:9998.
Point this proxy's --bw-host/port at the upstream Blastware ACH server.
