Bring npm package up to date with Github repo

[jhughes982]

The current version of the npyjs npm package seems to be behind the Github repo version, updating the npm package to match the repo version would be helpful.

You could consider automating the process of publishing to npm through Github actions (e.g. when pushing code or when accepting pull requests).

@jhughes982 — thanks for bringing this to my attention! I just released v0.2.1 to npm and will be working on getting this automated via github actions in the near future!
