Account for NVD Schema Migration from 1.1 to 2.0

[RTann]

NVD is migrating from schema 1.1 to 2.0. This migration also includes the retirement of its legacy data feeds in favor of an API-driven approach. See https://nvd.nist.gov/vuln/data-feeds#JSON_FEED and https://nvd.nist.gov/developers/vulnerabilities for more information. This issue is somewhat related to #165, as the API should be used before the legacy feeds are retired in September, 2023.

Thanks for letting us know! The good news is that we still have some time, will put this in our backlog though, we may get to it sooner or later.

Seems like the timeline has updated to December 15, 2023, so there is more time.
