Add sif.Update which accepts updates a SIF so that its content reflects the ImageIndex passed.

Any blobs in the SIF that are not present in the new ImageIndex will be removed from the SIF.

Any blobs that are present in the new ImageIndex, but not in the SIF, will be added to the SIF.

Blobs that are present in both the SIF and the new ImageIndex are not re-written. They will remain at their current descriptor location in the SIF.

My only other thought here is that it's a shame the GGCR Cache interface only supports caching layers (and not manifests/configs.) Otherwise it might be a nice way to hide some of the complexity of that. Oh well!
