I just noticed that there are many leftover .icc files in my /tmp directory: <img width="583" alt="image" src="https://github.com/rokka-io/imagine-vips/assets/941973/0a9330c4-c0e4-4c2b-9867-28fee1fef221"> I looked into the code, but couldn't find a spot where they are deleted after use. Is this a feature or a bug?
