Unnecessary root dependency on react

[JeremyGuinn]

You guys are fantastic for providing this package. I'd like to use this project outside of a react application, which apollographql/apollo-client supports. Could you follow the lead of apollographql/apollo-client to separate your core and react code? As was done here: apollographql/apollo-client#9940

Thanks for the feedback! I'd be happy to see the library usable outside of React. It'll take me a bit of time to play around with that /react entrypoint setup, if anyone wants to take that on feel free! Otherwise I'll look into getting this done when I can find time.
