Protocol buffers provide a binary format for storing data, but to work with them you also need the relevant schema defined in a .proto file--this would be publisher-settings.proto in your case. Protoc is ordinarily used for generating code to work with protocol buffers but it also has some encoding and decoding functionality built in for convenience.
What error are you getting when you run that protoc command? Here is another command you could also try: protoc --decode_raw < 2019-03-19T10_00.pb That version will decode the data as much as possible without relying on the schema, so its output will be less useful but it should at least give you a rough idea of what data is stored.
