React hook to dedup calls to an async callback.
Calls which are overriden resolve to the next 'winning' call's result.
/**
* React hook to dedupe async calls. The latest args wins.
*
* If idle, it runs the args on the latest callback immediately, returning the promise.
* If busy, it returns a promise that resolves to the next latest call, ignoring all intermediate calls.
