Hi, I am trying to store an encode protobuf in BigTable and I'm not able to insert binary data (represented as a Buffer) into a BigTable column. I have tried the following ways:

this.table.insert([
  key: `foo`,
  data: {
    event: new Buffer(),
  },
]);

this.table.insert([
  key: `foo`,
  data: {
    event: {
     data: new Buffer(),
    }
  },
]);

It seems to get stringified somewhere in the client library, which is making the data invalid.
