Cargo Vet Audit Failed

cargo vet has failed in this PR. Please run cargo vet --locked locally to check for new or updated unvetted dependencies.
Details about the vetting process can be found in supply-chain/README.md

If the unvetted dependencies are not needed

Please modify Cargo.toml file to avoid including the dependencies.

If the unvetted dependencies are needed

Post a new comment with the questionnaire below to the PR to help the auditors vet the dependencies.
After the auditors have vetted the dependencies, the PR will need to be rebased to pick up the new audits and pass this check.

Copy and paste the questionnaire as a new comment and provide your answers:

1. What crates (with version) need to be audited?

2. How many of the crates are version updates vs new dependencies?

3. To confirm none of the already included crates serve your needs, please provide a brief description of the purpose of the new crates.

4. Any extra notes to the auditors to help with their audits.
