Add AbortController to useAsyncEffect / useEffectOnMount

[schwartzworld]

In addition to all the other methods, it would be useful to opt out of a request if it's no longer needed. This should happen automatically if the hook unmounts. We might as well also expose a method in the return of the hooks so that a user can manually cancel a request if it's not needed.

const { data, error, loading, fireCallback, abort } = useAsyncEffect(someCallback)

return <div>
    <button onClick={fireCallback}>Make request</button>
    <button onClick={abort}>Abort/button>
</div>
