tugboat doesn't seem to work with private repo on docker hub.

Hi,

Thanks for making this nice lib.

I have a problem to pull images from a private repo on docker hub. I basically just followed the steps in README, like so:

import tugboat.AuthConfig
val auth = AuthConfig(user, password, email)
docker.auth(auth)().foreach(println)

docker.as(auth).images.pull(imageName).registry("https://index.docker.io/v1/").stream {
  case Pull.Status(msg) => println(msg)
  case Pull.Progress(msg, _, details) =>
    println(msg)
    details.foreach { dets =>
      println(dets.bar)
    }
  case Pull.Error(msg, _) =>  println(msg)
}

And it prints

Error: image .... not found

I confirmed that the same credential works with docker login. and from command line i was able to pull that particular image without problems.

Did I do anything wrong?

Cheers,
