Support for wasm bindgen

[drewm1980]

Feature Request:

It would be really nice to have tooling or at least canonical examples for js ndarray <-> wasm rust ndarray interop.

I know javascript doesn't support ndarrays as a language, but then again neither do rust or python, but we forge ahead anyways.

The existence of a nice binding generator PyO3 and packager (maturin) with ndarray integration is really nice, and allowed me to incrementally start introducing rust to a large codebase. It would be really nice to have that for javascript as well.
