Consider npm for distribution?

Hey, it would be neat to be able to npm install binauralfir --save instead of having to pull things manually. You can do this by publishing the module to npm which shouldn't be too hard since you already have a package.json.

It would go along well with all the other modules being written for WebAudio:
