codemod to upgrade to 4.5.0+

[sibelius]

does it make sense a codemod to migrate all hot(module) usage to only hot?

this code:

import { hot } from 'react-hot-loader'
const App = () => <div>Hello World!</div>
export default hot(module)(App)

will be transformed into this one:

import { hot } from 'react-hot-loader/root'
const App = () => <div>Hello World!</div>
export default hot(App)

I've made it here https://github.com/sibelius/react-hot-loader-codemod

let me know if you want to bring this code to this repo or add this to readme

That's awesome, and worth to be mentioned in a readme.
