Improve 'HTTP Security Features' checks with 'humble' HTTP headers analyzer

[rfc-st]

Good evening!.

I would like to suggest the use of my tool (https://github.com/rfc-st/humble) to enrich the 'HTTP Security Features' section; in case someone considers it can be useful, adding it or some of its findings.

Some details about it:

• MIT license.
• Featured, among others, in Kali Linux and OWASP 'Secure Headers Project'.
• 14 checks for missing HTTP response headers.
• 1132 fingerprint checks via HTTP response headers.
• 109 checks for obsolete or insecure/incorrect HTTP response headers/protocols.
• Can export each analysis to CSV, HTML5, JSON, PDF 1.4 and TXT.

Thanks!.
