[BOUNTY] - €40 - Convert existing Pioneer app to Homey 2.0

Hi Everyone,

I submitted a new test version which adding support for manually controlling the input source as well as using flow cards: input_source_changed trigger, input_source_is condition and input_source_set action.

The list of possible inputs is not complete, but I used the ones that were available in the app of Marco. Please let me know if something is missing or not working. Also some channels do not work for all Pioneer VSX devices. Sadly, I cannot change this because of some missing features of Homey.
