multiunzip from itertools but with support for larger than 12-tuples.
Converts an iterator of tuples into a tuple of containers.
many_unzip() consumes an entire iterator of k-tuples tuples, producing k collections, one for each column.
With default features, many_unzip supports up to 24-tuples.
Larger numbers can be enabled with feature flags, up to 192-tuples with the 192_tuple feature.
This function is, in some sense, the opposite of multizip.
