NodejsStreamOutputAdapter
is not yet changed...
For what is it used? is it still needed?

@jogibear9988 I am bundling jszip into my project and I feel like that your conversion to ESM very useful to reduce the bundle size, with or without treeshaking. From the workflow environments this repo runs on, the upstream is maintaining compatibility dating back to Node v0.x. Maybe we can collaborate on a fork instead and make this PR minimal?

I allready created a fork
see: https://www.npmjs.com/package/@node-projects/jszip

@jogibear9988 I mean, this is already a huge PR with ~20k lines changed. I do not think the author can review this PR and merge it someday.

I'm not sure if he ever will. As here are many open pull requests without any action.
But the changes are not so big, if you ignore whitespace changes, and also, that I've removed the bundeled files from the repo...
So if he only likes to merge the changes in the source files, this is not such a big task.

So what is your question?

As I said, I already created a fork.
Would you like to join?
