Allow for scanning of multiple hosts by reading from a file

[hackinaggie]

It would be great if users could specify a couple extra command line arguments to use multiple subdomains from a file that they found using other tools like subfinder.

Large companies have hundreds of subdomains and often times even though the base domain isn't behind cloudflare, maybe an obscure subdomain is. It should be a simple modification of cloudflair.py & cli.py that even I could implement if you would like.
