Summary:
Adding a split and shuffle attack :)
augmentation description: Splits the image into a grid of tiles (determined by n_columns and n_rows) and shuffles the tiles randomly. The resulting image is the concatenation of the shuffled tiles into the same grid format (resulting in an image of the same size)
