Docs: Importing Your Favorite JavaScript / TypeScript Package

[peterpme]

This is a common topic among beginners: how do I do this?

We can go over:

• using community versions of popular packages (bs-*)
• writing your own bindings for easy packages

I think it's worth pointing out that unlike DefinitlyTyped and the TypeScript ecosystem requiring everything up front, we can say, "hey, if you only need to type x, y, z, its super easy, you don't need to install the whole thing"

so as opposed to DefinitelyTyped folks, we apparently have many separate(possibly similar) bs-* bindings in the wild. imo to improve ReasonML engagement in the community, what about shipping Reason bindings in each of those pop packages/make a repo for DefinitelyBinded (I guess, redex already sort of solved this part) haha
