0961a88d7c parseEfiSignature: Don't rely on type of error code 
The specific error type is not part of x509.ParseCertificate documented
API. So we shouldn't rely on it for this workaround.

* AKPublic.Verify: Return an error if a provided PCR of the correct
   digest was not included in the quote.
 * AKPublic.VerifyAll: Implement VerifyAll method, which can cross-check
   that provided PCRs were covered by quotes across PCR banks.
 * PCR.QuoteVerified(): Introduce getter method to expose whether a
   PCR value was covered during quote verification.

Invert 'notspi' build tag to 'tspi' (#237) 
This change allows users to specify TPM1.2 support rather than remove it.
go-attestation will build without needing Trousers/TSPI support.
The flip-side of this is that TPM1.2 does not just work; TPM1.2 users need to
include the `tspi` build tag.

Ignore SBAT events in ParseUEFIVariableAuthority (#222) 
As part of the Boothole fixes, shim has introduced an
SBAT feature https://github.com/rhboot/shim/blob/main/SBAT.md.
SBAT configuration is configured to log to PCR7 using
EV_EFI_VARIABLE_AUTHORITY.
493bd940e5/mok.c (L228-L247)

This causes issue with ParseUEFIVariableAuthority, as
it asssumes that an event with type EV_EFI_VARIABLE_AUTHORITY
can be parsed as EFI_SIGNATURE_DATA, per section 3.3.4.8
of the TCG PC Client Platform Firmware Profile Specification.
