Subject: [PATCH] TFLITE_USE_DELEGATE has been changed to use
 GpuDelegateOptions instead of TFLGpuDelegateOptions.

When I tried to run the sample using the GPU-supported version of TensorFlow Lite, I encountered an exception on line 419 of tensorflow/lite/examples/ios/camera/CameraExampleViewController.mm.

The exceptions that occurred are as follows
"Unknown type name 'TFLGpuDelegateOptions'; did you mean 'GpuDelegateOptions'?"

Using GpuDelegateOptions seemed to be the right thing to do, so I modified the code to use this one.
