Okay, now it's working fine, thanks to @Dentrax.

You can test this with the following commands:

$ crane pull --format oci devopps/hello-world:buildinfo hello-world-oci-layout
$ tar czf layer.tar.gz README.md
$ LAYER_DIGEST=$(sha256sum layer.tar.gz | cut -d' ' -f1) 
$ ./crane mutate --append layer.tar.gz --oci-image-layout hello-world-oci-layout
$ tar tvf hello-world-oci-layout/blobs/sha256/$LAYER_DIGEST

Hey, sorry as always for the delayed review. 🥵

This is quite a lot of new code, which worries me since it doesn't have any corresponding tests, even e2e tests. I'm also not very familiar with the use case, so I'd like to understand that a bit more before committing to supporting this.
