Save radio

[sanbor]

Is your feature already implemented in the latest master? I don't think so

Is your feature request related to a problem? Please describe. When I go to a song radio, I get a nice playlist that I can't save

Describe the solution you'd like Save the radio or a playlist of the radio

Describe alternatives you've considered Maybe adding all songs to a new playlist and add all items, but I am not sure how to do this

Additional context In Spotify there is a plus button to save a radio, and I would like the same in spotify-player
