Use fetch_arrow_table for explicitly typed data

[d33bs]

Description

A new release of duckdb==1.4.0 changes the API for .arrow() returns to use pyarrow.lib.RecordBatchReader instead of pyarrow.lib.Table. This PR uses fetch_arrow_table to make CytoTable compatible with these changes and be more opinionated about what data type is used internally. Without this change CytoTable will encounter errors with installations of the latest duckdb.
