Protocol Buffer Code generation

By using the --protobuf flag, gen will generate a .proto file to describe the models generated from the database tables. It will also add proto struct tags to the generated struct.
You can customize the naming of the fields using the --proto-fmt flag. The generated .proto will be places in the --out directory.

--proto-fmt=snake proto name format [snake | camel | lower_camel | none]

syntax = "proto3";
