### Is your feature request related to a problem? Please describe. `magick` supports multiple frames for jxl, which is great. But apparently it makes no attempt to encode them with subtraction or modify any of the other frame-related features. Seemingly at the moment magick doesn't support any frame optimization? (Apologies, but if it does, they aren't easy to find documentation on.) Ideally it would be on by default, so that if you include the same file repeatedly, the output jxl doesn't get much bigger. ### Describe the solution you'd like New command line option to support (or disable?) frame optimization. ### Describe alternatives you've considered _No response_ ### Additional context _No response_
