 Review comment:
   Why is it called "...WithoutNulls" if it passes `with_nulls = true`?

> Writing a slice from row n of length m of an array to feather would write the 
> first m rows, instead of the rows starting at n.
> The null bitmap also ends up misaligned. Also tested and fixed in the pull 
> request below.
>  I've created a pull request with tests and fix here: 
> [Pullrequest#1766|https://github.com/apache/arrow/pull/1766]
