Use Rollup + TS to build Node version

Nodemon is a perfectly fine choice, albeit not so modern. Libraries like these are oftentimes built with rollup and TypeScript. I'm more than happy to set up the environment if you'd like.

I'd very much like that! Please note that the Node project has been moved into /node. Feel right at home and let yourself loose! :D
