Account for All Edge Cases

[GhostOf0days]

We have run into multiple failures on CMUEats because the Dining API doesn't account for all edge cases. I have provided a detailed outline of edge cases to account for in https://github.com/ScottyLabs/dining-api/wiki/Timing-Cases.

To account for these, we need to fix the timing logic in https://github.com/ScottyLabs/dining-api/blob/main/src/parser/diningParser.ts, starting at the following line:

const timeBuilder = new TimeBuilder();
