Import a scan
A scanner may also import an already existing XML file. This XML file should be completed, which means that it should be a final output from an Nmap scan. In case
the XML file was not completed (due to the scan being interrupted), use resume().
Example
import pathlib
import nmapthon2 as nm2
scanner = nm2.NmapScanner()
result = scanner.from_file('/tmp/nmap.xml')
# You can also use pathlib here
result = scanner.from_file(pahtlib.Path.cwd() / 'nmap.xml')
