This command is the CLI equivalent of making a web application page controller. It creates a command that can be executed via ./script/vendor command-name, along with the necessary support files and directories.

By default, the command will extend from Vendor_Controller_Command, which itself was created by make-vendor earlier. However, if you pass --extends=Vendor_Cli_ParentClass, it will extend from the named class instead.
