No functionality to save the html responses

Hi,

This tool is quite amazing. However, it lacks the functionality to save the html responses. Since, you are making GET request to all target you must be receiving the response body as well along with response code. I don't know much about go but this is what happens with python requests. If this is so, adding the functionality to save responses should not be a big deal. Please add this functionality if feasible.
