TODO: Get prebuildify integration fully working

[dfellis]

Now that it's been converted to Github Actions and build artifacts are working, it should be possible to write a publish script that downloads the artifacts, shoves the relevant pieces into the prebuildify directory, and then includes them in the artifact published to NPM.

But I've spent way more than the time I wanted to allot to working on this repo today, so this is a reminder to tackle this another day.
