[ADT] Add `zip_equal` for iteratees of equal lengths
Add a new version of `zip` that assumes that all iteratees have equal
lengths. The difference compared to `zip_first` is that `zip_equal`
checks this assumption in builds with assertions enabled.
This will allow us to clearly express the intent when working with
equally-sized ranges without having to write this assertion manually.
This is similar to Python's `zip(..., equal=True)` [1] or
`more_itertools.zip_equal` [2].
I saw this first suggested by @benvanik.
