feat: add corequisites field

This currently stores no information as no parser exists for it. I will
accept contributions for this, as it will likely take me a while to get
around to implementing.

The ideal goal we're aiming for would be to rewrite all the parsing
logic in nom. The only parser left is the "coursepoints" / requirements
parser. This parser has proven to be particularly difficult and
resistant to rewrites.

I expect this will take weeks, if not months to get around to. But, as
mentioned, contributions are very welcome.
