No metadata and stream control

[Koperbtw]

Hello,

I am currently experiencing issues with Snapcast when using it with both Librespot and Shairport-sync. Specifically:

• With Librespot, only the title metadata is displayed, and stream control is not functioning. Old patches do not work with the current version of Librespot.
• With Shairport-sync, stream control does not function. From what I have read, Shairport-sync supports stream control through MQTT, but I haven't found any information on how this can be integrated with Snapcast.

Could you please provide guidance on how to repair metadata and controls for Librespot and enable stream control for Shairport-sync?

Thank you for your help.
