Add a way to generate CommonJS modules

[Yu-Vitaqua-fer-Chronos]

Heya, i think it'd be useful if there was a way to use CommonJS bindings for Transcrypt? As some environments don't support import and export statements

If you are using a bundler like parcel or webpack, is this something that babel can do as a post processing step?

I have no idea as I'm not really a JS programmer and have limited knowledge of the ecosystem or how major packages work aha
