It seems like $console can also be of type Tarsana\Command\Console\OutTransformer and Tarsana\IO\Resource\Reader and Tarsana\IO\Resource\Writer; however, parameter $value of Tarsana\Command\Command::console() does only seem to accept Tarsana\Command\Interfaces\Console\ConsoleInterface|null, maybe add an additional type check?
