'''
Compatible with Keras, faster than reading from files (no stats).
It's only designed to work if all your images are vaguely similar sizes/
when encoded as JPGS, so if you have:
    white noise or other hard-to-encode stuff
    radically varying image sizes
    ...
    (probably other failure modes)
Then this is foolhardy.
