Refactor scraper to handle exceptions

[albertlyu]

Currently, the scraper works as intended for 13 out of the 30 team pages. 8 of the remaining 17 team pages pull data successfully, but switch the employee and title because of switched HTML tags. 2 pages have incomplete outputs and missing employees, 1 page returns an IndexError, 1 page returns a UnicodeEncodeError, and the remaining 5 team pages have significantly different HTML structures that will require separate scraping code.

Handle all of these exceptions such that all 30 team pages can be scraped into a single csv file with the same dimensions of information (team, department, subdepartment, employee, title).
