Buffered combineLatest

[griest024]

When multiple combineLatest sources emit at the same time (from an async perspective), I want the next emission of combineLatest to include the latest emissions from all of the sources. This is a pretty common use case in applications: where multiple subscribed pieces of state are updated from a single API call and a component will want to see updated data from all pieces of state (not just whichever one happens to win the race condition). Plus this will improve performance by reducing the rerenders from n pieces of subscribed state to just 1.

So I wrote a simple wrapper for combineLatest which accomplishes this. My question is, is there a creation function or operator already in rxjs that does this and if not, will you consider adding this feature?
