Add user-follow-read scope to allow getting followed artists

[phts]

I am making modification of spotify volumio plugin and possibility to access the followed artists. But there is no required scope for that in your lib.

So this is the missing scope.

Or please describe how to compile this library locally via docker image? What image to use and what commands to run? I will use it with my plugin then. I tried to follow https://www.docker.com/blog/cross-compiling-rust-code-for-multiple-architectures/ but no luck still... :pray:

Seems managed to build the binaries. But it required client ID of the app.

May I use existing one or I have to create my own and use it together with my integration?

Greetings, I no longer actively develop Volumio plugin, as my fork of librespot is quite old and outdated. Look at Volumio's fork of this repo - volumio/Vollibrespot for the current plugin's backend.

Also, there a lot of other developments in the years since - look at librespot-org/librespot or librespot-org/librespot-java or devgianlu/go-librespot that should use much newer API implementations.

Thanks, will look at it

I had time to look at your changes, this isn't such a big one, if you open it will merge it and make a release :-)
