Adding exfiltrate data option

[vrechson]

Hello, I created the -ed option to exfiltrate data. When enabled, it will analyze every DNS request and look for the following pattern: content.filename.extension.interactshdomain.tld. When the pattern matches, it will append every content sent to filename.extension, which means that changing this subdomains you may exfiltrate different files. I also added an example in the readme and the -silent option that will only hide the banner.
