Random rotation in training

[fukka]

Hi, excellent paper! I am reading your code. I see you have only random scale, random noise, random crop, and random color as data augmentation in donkey.lua. But you mentioned random rotation in your paper. Can you show an example of how to use it? I am mostly wondering how you handle the flow with random rotation.
