Error: Can't resolve 'fs'

When I added the lib to my react project I get the error in my browser console:

```
./node_modules/.pnpm/antlr4ts@0.5.0-alpha.4/node_modules/antlr4ts/misc/InterpreterDataReader.js 17:11-24
Module not found: Error: Can't resolve 'fs' in 'D:\frontend\node_modules\.pnpm\antlr4ts@0.5.0-alpha.4\node_modules\antlr4ts\misc'
```
