Support integration with Apache Paimon

Apache Paimon is a streaming data lake platform that supports high-speed data ingestion, change data tracking and efficient real-time analytics. OneTable could adopt Paimon table format for streaming lakehouse.

Start by reviewing Apache XTable's existing support for Apache Hudi, Apache Iceberg, and Delta Lake, then determine where Apache Paimon would fit in the cross-table converter. The issue is complete when OneTable supports the Paimon table format for streaming lakehouse interoperability, but it does not name files, tests, or a specific implementation scope.
