Doesn't seem to work with ESM builds for nodejs env

[amalitsky]

Since it is using deprecated Duplexer library, (with 15M weekly downloads btw) which has only CJS build to it.

Building my package with tsup (goes through fine) and trying to run the "binary", I get the following error message:

throw Error('Dynamic require of "' + x + '" is not supported');
        ^
Error: Dynamic require of "stream" is not supported

First line of duplexer's build is:

var Stream = require("stream")

And it is causing problems.

My ts config uses NodeNext as module and moduleResolution, and I have "type": "module" in package.json.

Once I drop gzip-size import from my code, all builds and works fine.

Let me know how I can help and thank you for the library! ❤️

Seemingly related issue with esbuild. I use tsup but these are similar tools.

Added repository with reproduction of an issue I'm experiencing.
