Feature: Lists Support

This pull request adds support for importing titles from lists in json and plaintext format, and thus allowing the powerful regex processing from title.go to be used for these lists. The following endpoints have been tested and are confirmed to work:

• https://mdblist.com/lists/garycrawfordgc/latest-tv-shows/json type: mdblist
• https://api.r4tio.dev/metacritic/upcoming-albums type: metacritic
• https://api.r4tio.dev/metacritic/new-albums type: metacritic
• https://bin.r4tio.dev/raw/iruripobuk type: plaintext
• https://sudoer.dev/movies.json type: trakt
• https://sudoer.dev/bluray.json type: trakt
• https://sudoer.dev/ant.json type: trakt
• https://sudoer.dev/tv.json type: trakt
• https://sudoer.dev/slu.json type: trakt

Example config:

  lists:
    - name: trakt-anticipated
      type: trakt
      url: https://sudoer.dev/ant.json
      filters:
        - 17
    - name: latest-tv-shows
      type: mdblist
      url: https://mdblist.com/lists/garycrawfordgc/latest-tv-shows/json
      filters:
        - 18
    - name: custom-titles-line-by-line
      type: plaintext
      url: https://bin.r4tio.dev/raw/iruripobuk # plaintext line by line
      filters:
        - 19
    - name: Upcoming albums
      type: metacritic
      url: https://api.r4tio.dev/metacritic/upcoming-albums
      filters:
        - 20

Possible improvements

• Set regbrr as a separate service (eg. arr and regbrr) or rename the current one to something like service
• [x] - Utilize brr api as a middleman for the regbrr jsons
