`ostree static-delta show` outputs this data - supporting exactly
this use case (tell me how much compressed data would be transferred
and how much uncompressed disk space would be used) was a top-level
goal of static deltas.

(We probably should have `apply-offline --dry-run --json` or so to output a machine-readable version of this)
