Convert images from TF evaluation to compressed jpegs

[lizlooney]

In cf_dataset_producer.py: Added a comment explaining why we convert the frame_data_image using PIL.Image. Removed special code for jpg format since we use png for the dataset.

In cf_model_trainer.py: Added code to convert the image we get back from TensorFlow evaluation to JPEG with lower quality. The JPEG images are about 25% of the size of the ones from TensorFlow.
