Research direction
The issue requests adding bitwise reading to file connectors. The feature is not yet implemented. The contributor should examine existing file source connectors in the SeaTunnel codebase (e.g., under seatunnel connectors v2/connector file) to understand the current reading mechanism. The implementation should support FTP, SFTP, HDFS, and local files. Consider base classes or interfaces used for file reading and how to extend them to support bitwise reading. No maintainer comments are available, so the contributor may need to clarify the expected behavior (e.g., configuration format, delimiter) in the PR.
