Raise a descriptive error if non-positive integer passed to in_groups_of.
This is more consistent than the current behaviour of raising a `ZeroDivisionError: divided by 0` error when 0 is given, which can be non-obvious especially if `in_groups_of` is part of a longer chain of methods. The negative case was ok - "ArgumentError: invalid slice size" - but this error is clearer still.
