Issue/539 typed paginated list

[bennettscience]

Original PR (#539) from garth74:

This pull request makes two changes:

Adds type hinting to PaginatedList so that elements used in for-loops, list comprehensions, etc. are typed (more info).
Adds negative indexing to PaginatedList.

Supports efforts of #435 and fixes #305 without preventing negative indexing all together (i.e., #306).

Updated to include upstream changes in develop since the original was opened in 2022.

I think there are two things worth discussing:

1. The typing improvements will help. I think PaginatedList is one of the harder bits of the library to get right if you've never used it before. It might help users in more complex cases avoid gotchas.
2. My concern is about negative indexing large lists. It still has to get all of the results before you can access the results. Should we (I?) put in some more effort to address the other related issues (see PaginatedList redux #114, #114 Implement __len__() for paginated_list #237, and Add coverage for retrieving an activity stream #175.)
