This PR still does not include support for fetching the list of available regions, list of movie providers, and list of tv providers.

However, I have added tests for the behavior it does support. I think this PR is still worth merging in, as I'm unsure when I'd have time to add support for the remaining parts.

Checked it a few times without really getting the heads-up you wanted to merge it without all tasks completed; going to check it now :-).
