This PR is there to look at the diff in the size of layers between two OCI images. This would be helpful in testing as I need to find which algorithm performs better. |

This should use ? here and below.

This is more succinct as if let Some(compare_with_build) = opt.compare_with_build.as_ref() {

Also, let's split the handling here into a separate function.

I wonder if this is more convenient as a separate CLI command that can take two arbitrary builds? i.e. rpm-ostree container compare-images? Or hmm, I guess if we're keeping it independent of RPM content it could live in ostree even as ostree container compare-images or so?

Would also make sense to have a handy fn print(&self) on ManifestDiff I think so we can share this code with the compose path.
