Fix packaging/distribution issues

[clintonb]

The postinstall script is being run after the package is installed. This works with yarn, but fails for pnpm. I would expect the compiled dist directory to be included in the download from NPM, not to require compilation post-download.

Consider the following:

1. Include dist in the package uploaded to NPM.
2. Remove the postinstall script.

@KurtzL thoughts on this? I'm not too familiar with npm packaging, but this is once again an issue. We don't ship tsc in production because we expect packages to have compile their own output.

Hello @clintonb , ok I see, the postinstall script will be remove. Also, I can add the .npmignore to clean unnecessary files. Thanks

@KurtzL that was my own misunderstanding. The postinstall script was the source of the problem. Thanks for the quick turnaround!
