New Binding - Antiference HDBaseT Matrix

Hi all,

I’ve created a first cut at a new binding for the Antiference HDBseT Matrix.

Might be pretty niche as not sure how many people out there have these but if you do and want to give it a go let me know.

Alpha binary can be found here: https://github.com/foxy82/openhab2-addons/releases/tag/Matrix_Alpha1
