Utility class for converting Substrait plans to SQL and extracting schema information.

Provides methods to: - Convert Substrait plans (serialized as base64 strings) to Calcite SqlNode representations - Extract Arrow Schema from Substrait plans - Convert between Calcite RelDataType and Apache Arrow types

This class uses Apache Calcite as an intermediate representation to bridge Substrait plans and SQL dialects, enabling connectors to work with query pushdown capabilities.
