Add browser fs fallback

[Ketler13]

This is an attempt to fix runtime browser issue - #2852 for environments like create-react-app where there is no possibility to manipulate webpack config without ejecting the application. I did this locally for installed antlr4 package and it helped me. Hope this solution is good enough.

Please also read webpack 5 migration notes :
Package authors: Use the browser field in package.json to make a package frontend-compatible. Provide alternative implementations/dependencies for the browser.

Ignore module in package.json

Thank you for the great tool!

I am having the same issue, any idea when we might expect an updated npm package with the merged changes?

[parrt]

We are actually doing quite a number of important changes so I don't have a date for you but I'm hoping within a month or so we can get 4.10 out the door.

Any news for this to be added in a release?

[parrt]

Finally got in major changes that I needed to make so I will start the release process over the next weak or two. sorry for the delay. This has been merged so it will show up in the release 4.10
