Compatible with typescript webpack without additional configuration

[MrRefactoring]

Webpack currently supports the creation of webpack.config.ts. But to import react-hot-ts/lib/transform need to add a esModuleInterop flag to tsconfig.json.

It would be nice to be able to not use this flag. For example make the export function rhTransform instead of export = rhTransform

I can create possible solution
