sev-snp-measure-go

This tool is a direct port of virtee/sev-snp-measure. Motivation to write this port is to integrate measurement calculation into Go tools.

The following limitations apply to this port atm:

• only supports SNP
• only measures the initial firmware

What this port does that virtee/sev-snp-measure doesn't do:

• parse OVMF metadata from a OVMF binary. This can be used (together with OVMFHash) to calculate measurements without having access to the binary.

If you need more features or find a bug please open an issue. For features that virtee/sev-snp-measure provides, addition should be quick.

Pull requests are welcome!
