> Currently we have a {{to_pandas}} method on {{Array}} and {{Column}} instances. The former produces a NumPy array whereas the latter a Pandas Series. We should add also a {{to_pandas}} function to {{ChunkedArray}} that produces a contiguous NumPy array of all the underyling {{pyarrow.Array}} instances.
