Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

Windows Defender exclusions for Visual Studio 2017/Android Studio/VSCode/Flutter

I've tried to strike a balance between performamce and security. I've commented out many of the individual file exceptions, however I also left the commented line for future reference/tweaking if needed. WSL2 only. WSL1 exclusions are different and not included here.
