Typescript needs to be a peer dependency

[jonnysamps]

Hi there, thank you so much for developing this plugin, it is awesome! However, I have a major problem: I can only use TS 2.* because it is a direct dependency of the plugin. We need to have typescript be peer dependency in package.json so we can use whatever version of TS we see fit.

I would like to use typescript v3. Any chance of doing this?
