Implement a Protobuf decompiler, which will be needed for testing and integration with languages without dynamic messages.
Add custom options to protobuf descriptors to hold meta-data that a decoding app outside SQL layer would need.
Generate Protobuf from AIS.
Add a test program. Needs to be an IT to get full DDL capabilities.
Make sure added columns have UUIDs.
Copy/paste error had sorting wrong.
Use TClass instead of Type.
