RFE: Integrate pyradio as an engine

[Baggypants]

Is your feature request related to a problem? Please describe.
OP-1 has an FM radio and we don't? Someone might like to play along to their radio? I have my zynthian next to me in the office and it's plugged in to the speakers anyway so it would nice to use it as a radio? It can also do playlists which might be good for gig accompianiment? I don't have a good use case really.

Describe the solution you'd like
Implement pyradio player.py as an engine that can be assigned to a layer. Instead of choosing a patch you'd be choosing a radio station from pyradios stations.csv. controls for start, stop, volume up & down and mute. Add MIDI control?

Describe alternatives you've considered
I've not really considered this one properly, let alone an alternative 😆

Additional context
I'm probably going to have a go at this using one of the cli engines as a template.
