Motivation for this change

Bump rustscan to 2.0.1 (version reports as 2.0.0, Cargo.toml still says 2.0.0 bee-san/RustScan#320)
./result/bin/rustscan -a 127.0.0.1 works

Since this is a breaking version change (1 to 2) change is there any documentation that needs updating?

Ignored new tests that required perl and python. Could add them but they don't look too valuable...

import sys

print('Python script ran with arguments', str(sys.argv))

my $total = $#ARGV + 1;
my $counter = 1;
 
# get script name
my $scriptname = $0;
 
print "Total args passed to $scriptname : $total\n";
 
# Use loop to print all args stored in an array called @ARGV
foreach my $a(@ARGV) {
	print "Arg # $counter : $a\n";
	$counter++;
}
