     Merges the specified observable sequences into one observable sequence by using the selector function whenever all of the observable sequences have produced an element at a corresponding index.

        - with: A second Observable<T> to zip with `self`
        - resultSelector: Function to invoke for each series of elements at corresponding indexes in the sources.

     - Returns: An observable sequence containing the result of combining elements of the sources using the specified result selector function.
