[IDEA] Media Receiver profile

[JarbasAl]

when the device is meant to be a full smart speaker there is companion software we could install to allow users to cast media from other services to the OVOS device

Possible integrations of interest:

• playercast
• NymphCast
• Spotify (using Spotifyd) - requires a paid Spotify subscription
• Airplay (using shairport)
• Squeezebox (using squeezelite)
• Snapcast + SnapcastMPRIS
• MPD server - list of clients
• upmpdcli - expose MPD server as DLNA renderer
• shanocast
• Bluetooth A2DP sink - some tips for rpi

In the future this could also include some companion plugins or skills to allow OCP voice search, eg, spotify support in ovos-media

This selection is based on what we originally included in buildroot, if i missed something @j1nx should have some extra ideas
