This PR follows up the discussion in #1466.

I did another round of practical tests with Skopeo 1.6.1 built on top of this change.
I was able to successfully copy to OCI layout format the following images:

Image reference Number of blobs Size on registry
quay.io/madeeks/pyfr:1.10.0-cuda11.2-openmpi4.1.0-ubuntu20.04 18 2.3GB
quay.io/madeeks/horovod:0.22.0-tf2.5.0-cuda11.2-mpich3.1.4-ubuntu18.04 23 4.1GB
quay.io/madeeks/gromacs:2020.4-cuda11.2.0-mpich3.1.4-centos7 15 2.3GB
nvcr.io/nvidia/tensorflow:22.01-tf2-py3 44 6.66GB
nvcr.io/nvidia/nvhpc:22.1-devel-cuda_multi-ubuntu20.04 13 8.14GB

Closes #1466
