Improve types for query

[calirvine]

Reimplements the types from #26 with some small improvements, and the runtime checks removed.

[calirvine]

This is the only real change (other than the runtime checks) from the previous PR. Introducing a generic here means that the return type can be inferred based on which column is passed.

@benvinegar I'm still seeing some prettier changes, I suspect it is because our editors are each picking up a different version. I think adding Prettier as a direct dev dependency should ensure all contributors are using the same version.

Even without the invariant stuff, this is a great improvement. Thanks!
