Replace react-rxjs with observable-hooks

react-rxjs is the library we've been using to connect our React components to view models and consume observables. However, after spending some time with react-rxjs, I feel that it's a very heavy-handed solution. It requires us to sprinkle <Subscribe /> and <RemoveSubscribe /> components all throughout the code, and makes React go through an extra render cycle whenever we mount a component that binds to a view model. What I really want is a lightweight React hook that just gets the current value out of a plain observable, without any extra setup. Luckily the observable-hooks library with its useObservableEagerState hook seems to do just that—and it's more actively maintained, too!
