It would be great to import a Spotify user's loved tracks.

Spotipy has a method for this (current_user_saved_tracks) so it shouldn't be too tricky to fetch them at least: https://spotipy.readthedocs.io/en/2.22.1/?highlight=current_user_saved_tracks#spotipy.client.Spotify.current_user_saved_tracks

However the Spotify API endpoint has a limit of 50 tracks at a time, with an offset property.
So we will need to fetch them 50 by 50 until we get all the tracks (the endpoint response also contains a total count, conveniently).
