[Feature Request] Playlist support

[cyclonejet]

Describe the feature you want to implement:

Create playlists, save them to .m3u file and read playlists from .m3u files.

Is your feature request related to a problem? Please describe:

No, but I'd like to listen to specific songs from my playlist.

Why do you think this will improve everyone's usage of Auxio?

So that everyone can start making playlists and shuffle/loop those songs only without having to skip songs.

Due Diligence:

• I have read Accepted Additions and Requests and the Contribution Guidelines.

Dupe of #36. I'm still planning this, but the implementation will have m3u importing/exporting while the actual way the playlists are stored is through an internal database.

Sorry, I did check the issues but must have missed. Thanks for fast response and a fast music app.
