[Feature Request] Add a web socket API to retrieve an image for a specific Spotify URI.

[rako77]

I want to add an API to retrieve an image for a specific Spotify URI (usually a daily mix so the image would change roughly once a day)

I'm wondering if I make a PR for this feature (I don't think it will be too hard to do) just wondering if you would accept a feature like this?

Sure.
