docs: // AddPortRange adds a list of ports where the first argument is the low bound
  // (inclusive) on the range and the second argument is the upper bound
  // (exclusive)
  //
  // E.x. AddPortRange(0, 1025) adds ports 1-1024 to the list
  // TODO(t94j0): Make into actual nmap ranges. (-p1-1024)
