Please don't bind to global

I haven't seen a package that binds to window in a long time. Better to make this a proper JS module, and let us do the binding ourself. It's 2021. We have great bundler tools now.

Hey Chadwick!

I think that could be a great improvement. I don't have the capacity to take that on at the moment. If you are interested, I'd welcome a PR to address that!
