[BUG] Users\Client->findAll does not paginate

[utdrmac]

Describe the bug
Using findAll() to retrieve all users only returns the first 100 users. Notion API docs indicate you must paginate using the 'next_cursor' after checking 'has_more' in the result. There is no option to provide this information to the function either.

To Reproduce
Steps to reproduce the behavior:

1. Use Users\Client->findAll()
2. Observe the returning array is only 100 elements

Expected behavior
Either A) findAll() should paginate automatically, and return the entire list of users, or B) provide some way to pass the cursor so the next call fetches the next page.
