isubrip 2.4.0 on Python PyPI

2.4.0 [2023-05-23]

iTunes links will now redirect to AppleTV and scrape metadata from there, as AppleTV has additional and more accurate metadata.
Improved error messages to be more informative and case-specific:
- If a movie is a pre-order and has no available playlist, a proper error message will be printed with its release date (if available).
- If trying to scrape AppleTV+ content or series (which aren't currently supported), a proper error will be printed.

A major refactor to the code, to make it more modular and allow for easier development of new features in the future.
Multiple changes (with some breaking changes) to the config file:
- The downloads.format setting is deprecated, and replaced by the subtitles.convert-to-srt setting.
- The downloads.merge-playlists setting is deprecated, with no replacement.
  If an AppleTV link has multiple playlists, they will be downloaded separately.
- The downloads.user-agent setting is deprecated, with no replacement.
  The user-agent used by the scraper, will be used for downloads as well.
- The scraping config category no longer exists, and is replaced by a scrapers category, which has a sub-category with settings for each scraper (for example, a scrapers.itunes sub-category).
Old config paths that were previously deprecated are no longer supported and will no longer work.
The updated config settings can be found in the example config.

This release includes a major rewrite of the code, which may have introduced new bugs to some core features. If you encountered one, please report it.
Minimum supported Python version bumped to 3.8.
beautifulsoup4 and lxml packages are no longer required or used.
