Generation of Protobuf .proto Files

[mikes-blend]

There are myriad tools in the ecosystem to generate types for all the various languages supported by quicktype, from proto files, but very little capable of going the other way. I feel this is a gap that quicktype is uniquely positioned to help solve.

Use case is this:

• An API specification already exists in one of quicktype's existing source formats. (TypeScript, JSON Schema, etc.)
• Developer wants to also provide Protobuf serialization or GRPC support for that API specification.
• Quicktype can generate the .proto definition file for the types in the API spec
• Other tools (protoc, gogoproto, protobuf.js), can generate a full serialization client from the .proto file

Challenges:

• How to ensure the Field Numbers remain consistent through generation of multiple versions of the .proto file.
