Feature - Create a event to track playback progress

Feature - Create a event to track playback progress and have it emit an event on the Websocket connection

The event could be something like

progress

• uri: The Track URI currently being played
• position: Playback position in milliseconds
• duration: Playback duration in milliseconds

I guess most ofthe work is still there with the "metadata" event - it just needs to be updated periodically and emitted as this new event

Reason:

There maybe a requirement for some applications to wait for playback progress to be pushed out to them rather than have to "Poll for it" on a regular basis (Say your implementing a playback progress bar) - Pushing out as a websockect event is generally more efficient than polling as you can have multiple clients "Listening" to a Websocket.

I think this could be done locally let me experiment

Yes, generally you can achieve this by keeping the timestamp at which you received the last position update and then do some calculations. That's how Spotify does it.

I am not closing this yet as it might be useful to have a feature where go-librespot pushes periodic updates, but not sure.
