Review comment:
I am not sure if using the `NextStripeReader` is correct here, see the
discussion about this on the original PR adding ORC dataset support:
https://github.com/apache/arrow/pull/10991#discussion_r698447362 (I initially
also used `NextStripeReader`, but so the name is a bit confusing, as it doesn't
iteratively reads the "next" stripe, it only reads batches from a single stripe)
