AMDRootCerts has changed to collect the x509 certificates into a pair type ProductCerts. This is backwards-incompatible with existing constructions of AMDRootCerts, so this release has bumped the "pre-1.0 major version", to 0.5.0. This refactor is paired with a fix to FakeKDS to fetch the product certs on construction since the default root certificates do not carry x509 certificates.
Internal testing of the go-tpm-tools integration on SEV-SNP hardware exposed this bug.
EDIT: Missed a couple changes that makes this a defective release.
