fix: replace babel require hook with a build step

The babel require hook is explicitly not suitable for libraries:
https://babeljs.io/docs/usage/require/ 

I’ve noticed that in trying to use this module, and trying to use the 
babel require hook as well, babel stops working. This patch removes the
require hook, adds a build process, and runs that build process before
a `npm publish` and `npm test`
