Get bookmarks with collections, date-times and comment threads

[bianchi-dy]

This is a ...
New feature (non-breaking change which adds functionality)

What does this PR do?
Scrapes the following information:

Author username
Users who have bookmarked a work, with tags, collections, date, and time
Comment threads (even the nested ones!) with users, date, and time

How was the change made?
Added new functions and columns per item, i.e. get_bookmarks, get_all_comments. get_all_comments is nested as a sort of hack since it uses recursion to get to the deepest level of the comment thread.

Things I'd like feedback on
Code elegance, I suppose? Or any stuff I missed in my merge

What next?

• Fix conflicts
• Check if everything is working with the new merges
• Working on a fandom analysis study with some friends from the YOI fandom! I'd like to credit this repository if we end up publishing anything, if that would be ok with you two.
