[Feature request] Better MPRIS support

[eyouga]

It would be neat to have cover art, loop, random and scrubbing support in mpris.

The mpris integration is currently as provided by upstream. This package used to add mpris support for Linux with a patch, as it was unavailable on Linux. This (my) implementation had album art.
Then deezer stopped using mpris-server and this patch was not compatible any more.

Please check out 7.0.140-4! Still some work to do, but it should be getting there.

On that note, I think it might be better to pin @jellybrick/mpris-service to a known good version, for security reasons.
