Show internet radio station if now artist is available in Cambridge Audio

[Solmath]

Breaking change

Proposed change

Currently the media control card does not display the current internet radio station for the CXN100.

For all the stations I checked, the artist is already part of the song title received from the station and the artist attribute is empty. Both the CXN100 and the StreamMagic app use the then empty artist spot to display station information.

To mimick this behaviour, the radio station should be displayed instead of the artist if the source is internet radio and the artist is not available.

I also added the media_channel attribute which contains the internet radion station now.
