[Feature] Integrate creation and deletion of CSV data into mongo within our algorithm

[surbhi-gulati]

Ticket 6: design doc -- judging algo refresh

• Add a 4th parsing function that pulls time strings from a CSV in to judging-algorithm/parser.ts
• In the same file, make calls to the controller to perform the DELETE ALL and then the CREATE operations in each of the functions using our server endpoints with Mongo
• Test your work by verifying that the 4 collections in Mongo are appropriately updated when the parser file is run, and that no extraneous old entries persisted in the database

You can look at past CRUD API work within this repository, implemented in tickets 4-5, as an example.
