Add support for using this as a global Babel plugin

It would be really awesome to be able to add this to the Babel configuration (if we can control it) globally as a plugin. That would allow one to use e.g. the tw prop on JSX Element without having to import "twin.macro" everywhere 👍

Not sure how hard that would be to abstract so feel free to close this if a macro is very different from a plugin.

The plugin is now up on npm 🎉 Thanks for all the work on this.

The way I understand it, babel-plugins visit the entire document while babel-plugin-macros visit specific nodes.

At the moment the tw prop part of twin already functions like a babel-plugin within the babel-macro so I’d probably need to adjust that function to allow interop with an external babel-plugin-twin.

I’ll have a better look into this and report back.
