Handling of throttled Spotify API calls

[alexpogue]

Hey Felix, thanks for the amazing library! Looks tons better than the old spotipy repo. Glad you took this over!

I found a possible issue - I get an error when fields parameter is specified for playlist(...). I would expect the function to return either a playlist or an object depending on whether fields is specified (similar to the behavior of playlist_tracks(...) at https://github.com/felix-hilden/tekore/blob/master/tekore/client/api/playlist/view.py#L117), but instead it appears to only ever return a FullPlaylist (see https://github.com/felix-hilden/tekore/blob/master/tekore/client/api/playlist/view.py#L73). Is there a reason you chose not to return a union of playlist and object for playlist(...)?

Thanks again, you're the best!

Thank you for your kind words!

Yeah, that's clearly just an oversight on my part. It should be similar to the tracks call. I'll fix it right away.

Expect this to ship with the next release!

And to clarify the references, somewhat embarrassingly I had to redo the commit twice. So the latest reference is valid. I'm still not quite accustomed to properly making release notes with each commit.
