title: ios Vision VNImageRequestHandler orientation issue
body: <p>I am trying to detect faces via camera using <code>VNImageRequestHandler</code> (iOS Vision).
  When I point on the photo by the camera in landscape mode it detects faces but with opposite orientation mode.</p>
  
  <pre><code>  let detectFaceRequestHandler = VNImageRequestHandler(cvPixelBuffer: pixelBuffer, options: [:])
  </code></pre>
