When used with the `--port` option, lot of noisy output is generated

I am using rustscan to search specific port in subnet with this command:

rustscan -a 192.168.178.0/24 -p 443,80

result are correct, but I get a LOT of such messages:

Looks like I didn't find any open ports for {:?}. This is usually caused by a high batch size

I know I can use --greppable to make it disappear, but it would be nice to have a better default behavior in this case.
