Research direction
First, review existing CyberChef operations in /src/core/operations/ to understand the pattern. Then, evaluate npm modules like 'pdu' or 'protocol data unit' for reference. The issue lacks specific PDU types, so comment on the issue to clarify scope (e.g., which OSI layer or specific protocol). Finally, implement a new operation class with encode and decode methods, following the existing structure.
