* This loader is to create special re-exports from a specific file.
* For example, the following loader:
*
* modularize-import-loader?name=Arrow&from=Arrow&as=default&join=./icons/Arrow!lucide-react
*
* will be used to create a re-export of:
*
* export { Arrow as default } from "join(resolve_path('lucide-react'), '/icons/Arrow')"
*
* This works even if there's no export field in the package.json of the package.
