DataLoader respecting EXIF data in Training Images (#3465)
* DataLoader will now bake in any transforms or image manipulations contained in the EXIF
Images may have rotations stored in EXIF. Training using such images will cause those transforms to be ignored while training and thus produce unexpected results
* Fixed the Dataloading EXIF issue in main DreamBooth training as well
* Run make style (black & isort)
