feat: add CVE, CPE and CWE from NVD Apis adapters

[dpgaspar]

Summary

New adapter proposal to support CVE, CPES and CWEs from NVD as a datasource.

Will consume 2 REST API endpoints from NVD, more details here: https://nvd.nist.gov/developers

for the CVES: https://nvd.nist.gov/developers/vulnerabilities
for the CPES: https://nvd.nist.gov/developers/products

Will allow for queries like (joining CVES and CWES):

SELECT 
  v.published_date,
  v.cve_id, 
  v.cwe_id, 
  v.cvss_score, 
  v.vendor,
  v.product,
  v.status,
  v.description, 
  w.description AS cwe_description,
  v.last_modified_date
FROM "cves://" AS v
LEFT JOIN "cwes://" AS w ON v.cwe_id = w.cwe_id
where v.vendor = "apache" and v.product = "superset"

Still missing tests, tell me if this sounds interesting to you @betodealmeida, or if it makes sense to add it directly to shillelagh
