Fix professors for sections not being scraped

[mehallhm]

NOTE: This is a redo of this PR to decouple this from the Yarn Berry stuff. Unfortunately, there had to be a little package patching to make this match that will have to be pulled out later.

Purpose

Scrapes the professors for a section. Because the Banner API removed this field from the search results when not authenticated through Northeastern SSO, this has to be acquired via a separate request to the section professor details page.

Tickets

• Closes Teaching faculty for classes not being scrapped #238

Feature List

• When scraping sections, fires an additional request to the section's professor details page to get the faculty information.

Notes

This is kinda thrown together and the implementation very much can be improved. For now, it gets the job done but the scraper needs some love... I think there is code in there that is tested but never used?
