Scanning multiple targets.

[leddcode]

Is your feature request related to a problem? Please describe. As of now, we can only scan one target at a time. My goal is to scan multiple targets from a file that I have provided.

Describe the solution you'd like Specify the path to a target's file when scanning multiple targets with the -ul flag. Each target in the list should be checked, one by one and without crawling. Finally, print a short summary.
