[cvss]: Unable to parse vectors with temporal score component

[ctron]

Parsing scores from the cvelistV5 repository make some scores fail with:

unknown CVSS metric name: `E`

It looks like there's a todo remaining for this:

rustsec/cvss/src/v3.rs

Line 5 in f79b59b

// TODO(tarcieri): Environmental and Temporal Metrics

I might be able to work on this and provide a PR if someone can review it.

Yep, we currently only support the CVSS v3.1 Base metric group, hence the type being cvss::v3::Base. The Temporal and Environmental metric groups are separate and currently unimplemented.

All that said, it would probably be good to add CVSS v4.0 support first (edit: opened #1087)
