Describe the solution you'd like
Being able to disable the banner by setting a flag in the config file.

~/.rustscan.toml

no-banner = true

Describe alternatives you've considered
Adding an alias to .bashrc. E.g. alias rustscan='rustscan --no-banner.

Additional context
The CLI flag behavior might need to change in case it's turned off with the config file, but then you may want to turn it back on when using the CLI without having to set the option in the config file.
