node-libnmap: how to enable infinite scanning?

Hi, how can I run the following nmap with the node-libnmap? I have tried to set the flags but to no avail. This is how I do infinite random IP scanning with nmap (from the nmap documentation…)

nmap -vv -Pn -sS -p 8080 -iR 0 --script http-open-proxy.nse -oX scan_results_8080.xml

I would like to just be able to scan for proxies and have the results via lib-nmap as processing the xml with a separate script isn’t optimal. Thanks for this excellent project also 😃 👍
