Some notes:
* The direct connection to the MPS4 server has not been exhaustively tested, please report any issues found.
* The only issue with the MPS4 connection seen thus far is that the setting SxDISPINFO as seen in the advanced rules below does not work.
* If the port is set to 5006 the binding will adjust its protocol to connect to a NuVo via an MPS4 IP connection.
* MPS4 connections do not support SxDISPINFO commands including those outlined in the advanced rules section below.
* If a zone has a maximum volume limit configured by the Nuvo configurator, the volume slider will automatically drop back to that level if set above the configured limit.
* Source display_line1 thru 4 can only be updated on non NuvoNet sources.
* The track_position channel does not update continuously for NuvoNet sources. It only changes when the track changes or playback is paused/unpaused.
