feat(pcr0tool): Add support of a logger

[xaionaro]

Adding basic support of a Logger to pcr0tool.

Test Plan

Ran:

go run ./cmd/pcr0tool/ -log-level=trace sum -hash-func sha256 -registers ~/firmware/northdome.registers ~/firmware/northdome.fd

Output:

The first line is:

DEBU[0000] FindEmbeddedFirmwareStructure err-result: <nil>

(as expected)

I know this took way too long on my side, sorry for that.

Can you rebase and fix, push and i will happily review and merge this week.

The PR is beyond recovery by now.

I know this took way too long on my side, sorry for that.

No worries. A lot of stuff changes since then, and logger was basically introduced as a side effect of other PRs anyway.
