Add `curry`/`uncurry` functions

Should use `curry`/`uncurry` from [`coconut-prelude`](https://github.com/evhub/coconut-prelude) but with better verification that the caught `TypeError`/`MatchError` actually is from a failed function signature.

Start by reading the coconut-prelude curry/uncurry implementations and the Coconut code that handles caught TypeError and MatchError exceptions. Determine how failed function signatures are currently identified; done means adding curry/uncurry while verifying that those exceptions came from signature matching rather than unrelated errors.
