Magnitude normalization for posterize and solarize

[marksibrahim]

Magnitudes are in range [1-10], but based on https://pillow.readthedocs.io/en/3.0.x/reference/ImageOps.html#PIL.ImageOps.posterize

solarize: range is [0, 256]
posterize: range is [1, 8]

Shouldn't the magnitudes be normalized in https://github.com/DeepVoltaire/AutoAugment/blob/master/autoaugment.py#L210 ? For example, line 211 would be

"solarize": lambda img, magnitude: ImageOps.solarize(img, 256.0 / magnitude)

All set, this is taken care of in ranges: https://github.com/DeepVoltaire/AutoAugment/blob/master/autoaugment.py#L173
