Let the driver keep announcing.
Keep track of when a message was received in the driver. If we don't
receive anything for a while, reconnect.
Don't connect twide in the manager.
The module advertizes itself on multicast and will trigger a new client
in the netjack2 manager. Tested with jack2 and 'jack_load netmanager'.
The driver will receive and send data (no midi yet) from and to the
manager in sync with the manager, without resampling and with a fixed
latency.
