[CI4] CLI

Hi,

Good Day!! Is it included in CodeIgniter 4 feature's the CLI like artisan in laravel? it's pretty cool.

I love CodeIgniter conventions and documentations and the way it is built but a CLI like artisan in laravel will make it better. A framework trying hard to adopt CodeIgniter way (FuelPHP) have it, they call it oil. Fuel is good but they have a very bad documentation. Hopefully this features will be available soon to CodeIgniter.
