Fix 'audiotrackdata'

Feature: Add more fine grained configuration steps (#28)

> ⚠️ Please read the following carefully:
> This release is a bit special. As "something" on Samsung's side changed,
> it is currently not possible to retrieve the status of "custom capabilities", eg.
> woofer, soundmode, eq, and others. Therefore I decided to give the option to
> disable the entities of these features as the value of these entities is not trustworthy.
> Instead I implemented all of these and more (thanks to @whitebearded) as service calls.
> Have fun using them!
