make two versions of ArgsParser.parse() - one handles ArgsException, the other throws ArgsExceptions

[AbUndMax]

one version directly uses the recommended ArgsException handling!

try {
        ArgsParser.parse(args);
        
} catch (CalledForHelpNotification help) {
        System.out.println(help.getMessage());
        System.exit(0);
        
} catch (ArgsException e) {
        System.out.println(e.getMessage());
        System.exit(1);
    }

so the user don't has to handle the exceptions

while the other method will not implement this but will throw the ArgsExceptions and asks the programmer to handle the code!
