Suggestion: overload `useSubscription` to add support for observer objects

The subscribe function of an Observable can receive an observer object:

const observer = { next: myNext, error: myError, complete: myComplete }

ob$.subscribe(observer)

It would be great if useSubscription allowed the same, so we can do this:

useSubscription(ob$, observer)

… instead of this:

useSubscription(ob$, observer.next, observer.error, observer.complete)

I’ll raise a PR.

Thanks for the fantastic lib btw. Migrating the Unsplash app over from rxjs-hooks, this is much more flexible.

Hey I haven’t had the chance sorry, I still really want it though!
