Reload on connection lost for LCN integration

[alengwenus]

Proposed change

The LCN integration is reloaded if the connection to the hardware bus is lost or the socket to the host coupler is lost/unresponsive.
Detection of unavailability is done using events which are fired by the underlying interface library (pypck).
