README Quick start: create a venv, pip install mx-multiplexer, generate the system rules, append peers/types, run two multiplexers, run backend.py and client.py; client printed b'HELLO' (also after the first multiplexer was stopped in the README flow not repeated). Probe: mxcontrol generate_rules to a fresh path under .coldpass.
