Suggestion: Add ngx_waf as a optional module such as naxsi WAF

[FlurryNight]

Hey, thank you for your work in this amazing script.

If possible, could u consider adding support for ngx_waf (https://hub.docker.com/r/addsp/ngx_waf-prebuild/tags), along with its modsecurity support with libinjection.

Describe the solution you'd like
I'd like this to be a option the user has and if yes, it would build the ngx_waf as a dynamic module and also build modsecurity for the system

Any updates?

Cheers
