kitdiff 📸🐱, a visual diffing tool

I got frustrated with the experience of reviewing image snapshot changes (from egui_kittest, thus the name) in my ide and on github, so I made something really cool:

Just run kitdiff in your terminal and it'll visualize all the diffs! You can use the 1, 2, 3 keys to switch between original, new, diff images. You can also generate diffs on the fly to play with different threshold options. Also, it's wicked quick!

but wait, there's more

You can do kitdiff pr https://github.com/rerun-io/rerun/pull/11253 to view a diff of that PR, you don't even need to check out the branch!
