hi, Dr. Stefan i'm sorry to bother, I have a simple question, I was working on a pr which need to use protobuf custom field, and I run into this problem here: https://github.com/golang/protobuf/issues/372  which I think is due to our codebase's protobuf vendor is too old `vendor/github.com/golang/protobuf`,  do you think I can update that vendor to lastest one ?  also I noticed there's also an extend package called `vendor/github.com/gogo/protobuf/proto` what's the releationship between those two ?  which one should I update ?
