Needs some extra work to handle the API changes on the new version, removing from the v0.5.0 milestone.

[dependabot]

A newer version of aws-nitro-enclaves-cose exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.
