Improve HTTP error handling.
Store HTTP response text in JustWatchHttpError, if error is related to the response message.
Otherwise (e.g. general connection, or timeout error) it's None.

Add monetization_types to OfferPackage

Handle more (hopefully all) HTTP errors, not just status codes.
The old exception is reused, with trimmed down fields to be more generic.

Fix relative links in PyPi description, for real this time.

Fix relative links in PyPi description.

Add "Releases" URL to pyproject.toml.
Capitalize "Changelog" URL name.

I don't really know what would it mean for this project to reach 1.0.0/stable, so here it is anyways.

Change error handling - add new exceptions instead of asserts:

• JustWatchHttpError - API responded with a non-2xx status code
• JustWatchApiError - response from API has errors in JSON
• JustWatchError - parent for all other exceptions for easier catching

Add a lot more comprehensive documentation, created with Zensical.

Change license to MIT.

Update "Usage" in README.md so it's up to date on PyPi page.

Update README.md ToC so it's up to date on PyPi page.
Also added missing unit tests.

Add two new functions:

• popular - looking up currently popular titles
• providers - get data about service providers (like "Netflix") to use in filtering in popular or search

popular and search allows for basic pagination with offset parameter.

search can now be used without specified title, making it oddly similar to popular, but oh well. I figured it out after popular was ready.
