Feature/strict temporal validation

[JesusMcCloud]

• Update to WARDEN-roboto 1.7.0
  • Android attestation statements (for SW, HW, but not Hybrid Nougat Attestation) do now verify attestation creation time!
  • Refer to the WARDEN-roboto changelog!
• Change Android verification offset calculation:
  It is now the sum of the toplevel offset and the Android-specific offset
• Change the reason for iOS attestation statement temporal invalidity:
  • It is now AttestationException.Content.iOS(cause = IosAttestationException(…, reason = IosAttestationException.Reason.STATEMENT_TIME))
    • This reason was newly introduced in this release, making it binary and source incompatible!
  • iOS attestations are now also rejected if their validity starts in the future
  • The validity time can now be configured in the same way as for Android, using the attestationStatementValiditySeconds property
  • Any configured verificationTimeOffset is NOT automatically compensated for any more. This means if you have previously used a five minutes offset, you now have to manually increase the attestationStatementValiditySeconds to 10 * 60!
