Description
Is your feature request related to a problem? Please describe.
It seems some datasets may have a few images which aren't oriented the right way, while the metadata of underlying image file gives the orientation.
eg: open_images_v4, 0000587b9647679e.jpg
Describe the solution you'd like
Image should automatically be rotated by TFDS at preparation time.
Bounding box if any should also be rotated? (or optionally so)
Describe alternatives you've considered
None

Research direction
Start by locating the TFDS image preparation path and the Open Images v4 example named in the issue. Determine how image orientation metadata should affect images and whether bounding boxes must rotate as well; done means prepared images have the intended orientation with a defined bounding-box behavior.
