Speedup OneDrive backup by pulling urls in delta API (#1842)
## Description

This brings in another huge improvement in the backup speed dropping from ~15m to ~1.5m for an account with ~5000 files. This one also drastically reduces the number of requests we have to make for the same account from 5505 to just ~55. This also means that we don't get throttled anymore and we can easily run multiple backup jobs in parallel before we hit the 1024 limit.

~The code works as of now, but I have to double check the numbers as well as fix an issue with us opening too many files and causing program to crash with 'too many open files' when we bump up the numbers. With the current numbers, it works, but I wanna double check and optimize them. Plus some code cleanup.~
