Description

Currently, we use next_batch -> Result<Option<RecordBatch>> to iterate over batches. However, this is very similar to the iterator pattern that Rust offers.

This issue concerns migrating our code from next() -> Option<Result<RecordBatch>>

on the trait Iterator, so that we can leverage the rich Rust iterator API.
