Color profiles of are not handled by the scripts

The script treats all images as sRGB even if they have color profiles.

Handling of color profiles needs to be added in image loading.

https://github.com/kohya-ss/sd-scripts/blob/2857f21abf6ed53abe89dd512b3bf25fd2913e03/library/train_util.py#L2490

Something like this:

image = Image.open( path )
icc = image.info.get('icc_profile', '') # Get color profile in the image
if icc:
src_profile = ImageCms.ImageCmsProfile( io.BytesIO(icc) )
srgb_profile = ImageCms.createProfile("sRGB")
image = ImageCms.profileToProfile(image, src_profile, srgb_profile) # Convert image to sRGB

Start at library/train_util.py around line 2490, where images are loaded, and inspect how the current loading path handles embedded color profiles. Use the issue's Pillow ImageCms example as the reference; done means profiled images are converted appropriately to sRGB instead of being treated as unprofiled sRGB.
