build a single transloadify binary

[kvz]

We could use e.g. https://github.com/vercel/pkg to build a single binary, this way, people from outside the js ecosystem will have an easier time wielding it.

This was an idea by @ethanwillis - we thought about porting to Go. This would result in a tinier and likely faster binary, but also in a complete rewrite, and less of our team being able to help out. So perhaps building the existing codebase has more viability.

We should first do #25 though

I already have the same setup for another cli app ezshare which works quite well, so can do it similar to that.
