Frank King 97c953f561 Add Iterator::map_windows
This is inherited from the old PR.

This method returns an iterator over mapped windows of the starting
iterator. Adding the more straight-forward `Iterator::windows` is not
easily possible right now as the items are stored in the iterator type,
meaning the `next` call would return references to `self`. This is not
allowed by the current `Iterator` trait design. This might change once
GATs have landed.

The idea has been brought up by @m-ou-se here:
