[huesync][WIP] Hue Play HDMI Sync Box Binding - Initial contribution

[pgfeller]

This binding integrates the Play HDMI Sync Box into openHAB. The integration happens directly through the Hue HDMI Sync Box API.

The beinding is using mDNS to discover HDMI Sync devies in the local network. The LED on the Sync Box must be white or red. This indicates that the device is connected to the Network. If the LED is blinking blue, you need to setup the device using the official Hue Sync App.

Community discussion thread: Philips HDMI Sync API

Closes #10218

Credits
The code is based on the work done by Marco Kawon - but the code is refactored. Feedback is very welcome. The refactoring is done to implement functionality step-by-step, so that I understand the code and in the hope to simplify it a bit (e.g. the json serialization).

@andrewfg Thanks! Take your time - progress will be slow unfortunately; as free time is a rare commodity ...
