Description
Is it possible to have a parquet file with NullType/UNKNOWN column?
Further more, is it possible to have another parquet file with NullType/UNKOWN column that has non-null value? I'm not sure if it fits into bad_data or not as this is allowed by spec but libraries handle this situation differently.

Research direction
Start by checking the Parquet specification for NullType/UNKNOWN columns and the repository's existing bad_data cases. Determine whether files with null-only columns and non-null values in an UNKNOWN column are valid fixtures, then document or add coverage for the expected handling once the behavior is established.
