Both .in or .out options have to be specified for field_mask field #3

In case only one of .in or .out options is specified for a FieldMask field the generation fails. Example of failing proto file:

syntax = "proto3";

import "google/protobuf/field_mask.proto";
import "fieldmask/option.proto";

message UserInfoRequest {
  string user_id = 1;
  google.protobuf.FieldMask field_mask = 2 [
    (fieldmask.option.Option).out = {gen: true, message:"UserInfoResponse"}
  ];
}

message Address {
  string country = 1;
  string province = 2;
}

message UserInfoResponse {
  string user_id = 1;
  string name = 2;
  string email = 3;
  Address address = 4;
}
