v0.3.0: New onQueryComplete API, add size information

onQueryComplete now has a new API which returns an object as the second argument to the callback, and also returns the size information of the response from the database:

inspect(r, {
  onQueryComplete: (query, { size, time }) => {
    console.log(query, size, time);
  }
})

This will allow for more extensibility in the future.
