Hive query results schema column names do not match the target Iceberg column names.
Instead we have to rely on the column order. To keep the other parts of the code generic we fix this with a
wrapper around the ObjectInspectorPair. This wrapper maps the Iceberg schema column names instead of the Hive
column names.
