test: Add a manual test to simulate DTMF handling in osmo-sip-connector
Add a manul test to the contrib folder that helped and can help during
the development of osmo-sip-connector or similar software. This avoids
having to create a separate mncc module.
It can be started like:
$ PYTHONPATH=$PWD/../ python manual_test_server.py
