> Given a ChunkedArray, an Arrow user must currently iterate over all its chunks and then cast them to their types to extract the primitive memory regions to access the values. A convenient way to access the underlying values would be to offer a function that takes a ChunkedArray and returns a C++ iterator over all elements.
> While this may not be the most performant way to access the underlying data, it should have sufficient performance and adds a convenience layer for new users.
