chore: convert JSDoc comments to TSDoc

[dsanders11]

Most of the "conversion" here is simply deleting @param and @returns which are only types, since they're redundant to the TS types, sometimes wrong, and TSDoc doesn't include types for obvious reasons.

I assume TSDoc will just have stub docs (with name and type) for params that aren't explicitly documented?

[dsanders11]

@itsananderson, I believe so, yes. It can pull the parameter names and types from the code itself, the @param comments just supplement those with additional information.
