Implement AniList module

[No767]

Summary

Aims to close (#566) by fully implementing AniList support. Previously, only searching for anime/manga was allowed, but now, this time there is full support for this module. The /search anime and /search manga commands have been merged into one command, /anilist search with dedicated flags for searching, sorting, and many more. In addition, characters are now displayed within search queries on their own pages, and others such as studios, users, and others will be added soon.

To-Do Checklist

As of now, this is the current list of tasks that needs to be done in order for this PR to be complete:

• Searching for characters
• Charcter inclusion within /anilist search
• Dedicated searching for studios
• Dedicated searching for staff and users
• Reviews (<2000 characters) within /anilist search commands
