Question: -e should already exclude -waf?

here would be nice to accept as input

Domains
URLs
ASN
IP
IP:port
IP/CIDR

• exclude-ips /match-ips would be great if was ips/cidr https://github.com/projectdiscovery/mapcidr/issues/48

• also filter/match for cdn/cloud/waf https://github.com/projectdiscovery/httpx/issues/570

-fcdn <filter cdn>
-mcdn <match cdn>

-fcloud <filter cloud>
-mcloud <match cloud>

-fwaf <filter waf>
-mwaf <match waf>
