Show HN: JavaScript Bindings for the GGML

This is using N-API rather than WASM or process piping. So theoretically, it should be more efficient.

It's just a working PoC right now. My next step is to rewrite some GGML examples in JS, and refine where it feels rough.

Only macos is supported at the moment, linux builds fine but is not published to npm yet. Windows build is broken.
