It's not obvious to users if this is the same value as tpm2-tools or the reconstructed value.

tpm-eventlog: Correct the display of final calculated PCRs
...
Although the calculation matched on my machine the actual numbers didn't
match PCR0 values from the tpm2-tools. This was a display error.

tpm-eventlog: Replay the TPM event log to get the PCRx values
...
In theory, these should always match the reported PCRx values from the TPM.
If the reconstructed event log checksum does not match the TPM value then
something is either implemented wrongly, or something bad has happened.

Add a new plugin that can parse the TPM event log
...
Some devices do not have a stable PCR0 for the same firmware version, and I'd
like to collect the TPM event log for affected machines to debug why.
