React strict mode fix by modifying usage of new lifecycle method

[pcast01]

Thanks so much for you library. I use it and I want to help out.

I wanted to add the lifecycle method getDerivedStateFromProps.

I am putting my own app thru React.StrictMode and came your library uses componentWillReceiveProps and this will just prepare your library to be up to date for used with React.Suspense and React.lazy(). Let me know if I can help out.
