Get Media Library returned by the playlists.json request.

[LiamKarlMitchell]

Hi, the method parsePlaylistEntries ignores the other nodes returned such as "Media Library".

Would be nice to expose these as well.

Perhaps a getPlaylistRaw()

Maybe the request method could be public?
public async request

Hi, making the request method public makes a lot of sense.

As for the playlist ignoring nodes, I deliberately chose this because I never used the other nodes and in my view they had no use case. I will implement them when I go over the package again.
