Remove typescript from dependencies

[ismay]

A place to continue the discussion from #49 (comment):

Still feels weird to bundle typescript as a dependency btw, when it seems more appropriate as a peerDependency. Maybe good to discuss that in another issue, don't know how you feel about that?

Yeah why is it it's a dependency by the way? It shouldn't need to be a peerDependency either should it? As in, if you don't use Typescript you shouldn't need it, couldn't we just make it a devDependency since the only reason we have it here is for testing, right? Or am I missing something?

I think we did that because typescript-eslint-parser throws if typescript can't be found (or complained anyway). Which is annoying for people who don't use our processor for typescript as they have no need for typescript in their project. So we're basically stuck with this situation unless it can somehow be fixed on typescript-eslint-parser's end (by not doing the check until it's actually instantiated or something, don't know what they're doing exactly).

Hmm that's a pain <.<. When I'm done reviewing this which should be in a sec I'll just look at our code regarding Typescript as I have never looked at that, mostly out of curiosity, would be awesome if we could remove that dependency somehow for sure though it doesn't sound like it.
