Please publish the npm package

This is a great library! Thanks for developing and sharing.
@jpambrun Would you mind publishing the npm package?

I found it useful in extracting the data from some weather forecast models: https://github.com/archmoj/opengrib2

If you need it in node you might be better off writing a small native binding.

This is based on a now fairly old version of openJpeg and it would need some non trivial effort to update. Targeting wasm would also be nice.

Unfortunately, I don't have time to dedicated to this in the near future.
