Add caveats to README #42
Description
This completely slipped my mind when first writing the README, but I think it's important to have a section that explains all of the caveats of the scraper project. This can include but is not limited to:
- Ever-changing data on the SIS platform
- Potential future incompatibilities with new data
- Assumptions made in order for the scraper to work
- Precautions taken to maximize flexibility of the scraper
This way, users would be able to take a guess as to what may be wrong in the case that the scraper breaks in the future.
