* 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.
A go-fuzz target for the ParseEventLog function. It has been tested
with go-fuzz and go-fuzz + libFuzzer.
oss-fuzz requires a statically built fuzzer binary, so `gofuzz` build
tags are added to avoid building files that depend on go-tspi. A mock
tpm_other.go file is also included to satisfy the `platformTPM`
interface.
