How to check for fields in message that are not in proto file definition

[guikubivan]

Using protobuf3 and just realized some fields were not being encoded because I was using snake case, where it seems protobufjs expected camel case, so would like to have a utility function that checks if I'm including fields that are not in proto file definition.

I guess I can add one myself, but wanted to see if I that exists already. Also, is the camel case field names a protobuf3 language thing or is there a way to use snake case in message fields since my proto file uses snake case?
