D. Ulis 8cdc182aff CIP: Attribute updates 
1. Switched to common way to parse Get Attr All, using dissect_cip_get_attribute_all_rsp, for CCO (class version) and CIP Validator. This also fixed a missing attribute in the old CIP Validator code.
2. Add cip_string2 attribute implementation
3. For CIP Validator, set the protocol as "CIPS Validator", previously this was "CIPS Supervisor".
4. For classes with subdissectors, add the service to the Info column in the response.
