[Feature] Samsung SmartThings API support for Input Source, etc.
Add  (additional) support for the SmartThings API, which will allow direct/instant query and setting of Input Source among other features not possible with the remote control API being used right now. It will solve a number of the shortcomings listed on the first page of the Wiki, including: checking current channel, volume, mute status, source selection.

I briefly mentioned this in another post, but I'm creating a dedicated feature request for it now after finding multiple code examples where this feature was added to previous integration that, like homebridge-samsung-tizen, were using the V2 API or legacy remote control APIs exclusively. In short: the developers were able to integrate SmartThings support without refactoring their whole projects. ;)
