Add the ability to create playlists in Qobuz provider

Currently, Qobuz playslists will sync 2-way only if they are created on the Qobuz side. On the MA side, they have to be created in the built-in provider, and they don't sync to Qobuz.

Other streaming music providers reportedly allow creating playlists within MA. I'm just asking for the ability to do the same with Qobuz.
