Provide support for `waldo add` and `waldo build` for React Native (non-Expo)

[edelans]

same as #20, but with React Native

@eBardX looks like React Native builds generation will be very close to what you did with xcode https://qmo.io/blog/creating-react-native-simulator-builds-in-app-center

@eBardX do you know if it's reasonable to push it through the finish line?
(If there is "just" a few hours left, it would be a pity not to do it)

I do have it working, I was just holding it back so that we could release a complete React Native solution (both Expo and non-Expo support). But it looks like the Expo/EAS CLI is not merely a superset of the non-Expo React Native CLI — it is a complete rewrite that seems to use nothing of the original. (In fact, I am pretty sure it actually uses Fastlane underneath to do some of its “magic” — a truly scary thought.)
