Original GitHub issue: https://github.com/devgianlu/go-librespot/issues/194

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.

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.
