Think about publishing packages to NPM registry instead of GitHub packages

[eddyloewen]

As I found out today it is not possible at the moment to read npm packages from the GitHub Packages registry without a personal access token. Even for public repositories/packages...

This is very unfortunate...

By digging deeper I found that this will probably not be solved in the near future: https://github.saobby.my.eu.orgmunity/t/download-from-github-package-registry-without-authentication/14407

So maybe we should start publishing to the real NPM registry ?

This would also resolve #17
