I've skimmed briefly and the changes look reasonable - will look more in depth on a separate occasion when I have more time.

Not for this PR, but I wonder if there would be some benefit in a `--decode-crel` and/or `--encode-crel` option that would convert an object file to/from using CREL. I feel like this might be useful for experimentation, or for handling the case where an object was generated with CREL but needs to be usable by an older tool that doesn't understand CREL. Equally, it could be useful for retroactively encoding CREL when the feature wasn't used during original creation of the object. Thoughts?
