RandomErasing

Also written: RandomRotation, RandomPerspective, GaussianBlur, TrivialAugmentWide

One of several image augmentations: `RandomErasing` blanks a random rectangle, `RandomRotation` turns the photo, `RandomPerspective` skews it, `GaussianBlur` blurs it, and `TrivialAugmentWide` applies one random change of random strength. Some, like erasing, can hide the evidence for a label such as damage, so they may not keep the label true.
