Creating an Aggregated Iterator with Fillvalue

Create an iterator that aggregates elements from each of the iterables. The iterator returns pairs of the form (i, val), where i is the index of the element from the iterable and val is the element obtained from the iterable. The iterator stops when the shortest iterable is exhausted, applying fillvalue for the missing values.
