Module transcode 

JSON <-> protobuf transcoding for the +json codec.

grpc-webnext carries opaque message bytes; the envelope (frames, trailers) is always protobuf, but the application message may be JSON. Converting JSON to the binary protobuf that a gRPC handler expects (and back) needs the message descriptors, so a Transcoder is built from a compiled FileDescriptorSet (e.g. protoc --descriptor_set_out / prost_build ... file_descriptor_set_path).
