TPM attestation parser does not correctly handle ECC keys in pubArea

[aseigler]

When parsing the unique field from pubArea during an attestation verification, unique is a TPM2B_PUBLIC_KEY_RSA only if the TPMI_ALG_PUBLIC is TPM_ALG_RSA. If TPMI_ALG_PUBLIC is TPM_ALG_ECC, unique is a TPMS_ECC_POINT. See TPM Rev 2.0 part 2, structures, section 12.2.3.2.
