Add support for Photometric stereo (PS)-AD dataset

[jpcbertoldo]

[1] recently published a dataset similar to MVTec-AD with photometric stereo images -- each object has 4 images with exactly the same position but with different illumination angles (example below).

Describe the solution you'd like

Create a dataset and datamodule for this dataset.

This should probably wait for #572.

Additional context

The paper (version from the 18 October 2022, link below) says (footnote 1) "Dataset and codes will be available when this paper becomes public.", so I believe it has not yet been published.

[update]

The paper's code is available here: github.com/Junyong-Jung/PSAD

The dataset is availbla for download here (~100Gb): cnu365-my.sharepoint.com/:u:/g/personal/jjy9385_o_cnu_ac_kr/EeAfcf2zU9NCoz8KjhpeJA8BA5Xv6gp0yxryw-o5AsSUXw

Size of the train/test sets for the 10 categories in the dataset (numbers in terms of instances of object, the number of images is multiplied by 4).

Thanks @jpcbertoldo, looking promising! Moving to feature requests for now.
