Add an option to check from list of subdomains

[deathflash1411]

So I use multiple tools to prepare a list of subdomains (amass, assetfinder, subfinder). Add the functionality to directly check for subdomain takeovers from a given list of subdomains, this option must run subfinder to enumerate subdomains it should directly check for takeovers from the given list of subdomains.

We can add reading subdomains from file and skip the subfinder step for sure. Could be interesting to be able to pipe into Rupert like you see with HTTProbe, as well.

Donald will add the read from file option tonight.
