Include url response body in the callback function OnResult.

[fetlife1]

Would be nice to have http response body in the callback response, for example as a ReponseBody field in the Result struct

 OnResult: func(result output.Result) { // Callback function to execute for result 
      fmt.Printf("respone body is %s\n",result.ResponseBody)    
    },    
  } 

Use case: Useful for scanning the website's html code without having to the request the same url again for example looking for secrets or running a regex across all found endpoitns, saving time and resources for the developer, and http response is probably laying around in some variable, might as well make use of it :)
