Extend exclude pattern functionality

[Mzack9999]

Please describe your feature request:

exclude-cdn and exclude-private-ips should be deprecated, then merged and extended into a unique exclude flag that accepts:

• CIDRs (x.x.x.x/y)
• Hosts (*.scanme.*.sh)
• Regexes (^test$)
• CDNs (cdn)
• Private IPs (private-ips)
• Ports (*:8080)

Example:

httpx -exclude cdn,private-ips,http://*scanme.sh,*:8080,1.0.0.0/24

Each tools has its own implementation, hence it would be interesting implementing it as a shared logic that could be plugged into all of them. For example we can add a callback to fastdialer.OnBeforeConnect where we check all supported patterns.
