Function ProtoWireToJSON

utils/grpc.go:351–374

ProtoWireToJSON takes a MessageDescriptor, compiled files, and a wire-format []byte, and returns the JSON encoding ([]byte). The files parameter is crucial for resolving google.protobuf.Any types which require access to all message types in the compiled schema.
