Exclude option for images

[sulaweyo]

It would be great to have the option to exclude specific images from the cleanup. So basically --images-like but as an exclude pattern.

I have a lot of images in my registry and 99% can be cleaned with this tool just fine, thx for that 👍
I just have a few images that are often built by the CI where i need to keep versions in between like sprint versions. For these images the build does a cleanup of older tags so i would need to exclude them but do the cleanup on all others.
