Image preprocessing

Instead of using specific image preprocessing (mode='imagenet') as

    x[..., 0] -= 0.485
    x[..., 1] -= 0.456
    x[..., 2] -= 0.406
    # Scaling
    x[..., 0] /= 0.229
    x[..., 1] /= 0.224
    x[..., 2] /= 0.225

the mode='tf' that rescale pixel value to [-1,1] is preferable and could avoid unwanted effect when applying training with the other datasets/networks.

The original version (master) of srl_zoo has 5719 lines of code. My pull-request has already added and removed +4145/-1453 lines of code, thus 5598 lines of code have been modified (~97% of code). There is no need to be merged to the master branch.
