Using protobuf on message types #60
Description
Is your feature request related to a problem? Please describe.
In message exchange using the current protocol, the struct defined in types is serialized to gob and transmitted.
However, this is dependent on the go language and has the inconvenience of having to define each method one by one.
Describe the solution you'd like
Uses google's protobuf. This allows for cleaner message type definitions and cross-language compatibility.
Additional context
It would be good to consider whether there are other good libraries besides protobuf.
