TypeScript types should be moved to DefinitelyTyped or ported to TypeScript

[nickserv]

This is pretty much the same as reduxjs/redux#3500, so please read that for my explanation and the pending discussion.

Ultimately the decision for Reselect depends on how comfortable the maintainers are with TypeScript and if they want to support it directly (is so port, if not use DefinitelyTyped and remove the types from this package).

@markerikson @timdorr react-testing-library moved their typings to DT, but added them as a dependency to their package. Could be an interesting move for reselect/redux-thunk/... too if you want to keep them in JS.

In my opinion, it's better to break back compatibility and allow more freedom in versioning the peer dependency.

Don't see them being moved to DT at this point, and if anything we oughta rewrite this in TS.
