Add new IsInterfaceRule

[jesperbeisner]

Hey everyone,

I would like to check that all classes in a specific namespace are interfaces. Something like this:

public function testAllClassesInNamespaceNeedToBeInterfaces(): Rule
{
    return PHPat::rule()
        ->classes(
            Selector::inNamespace('App\Interfaces'),
            Selector::inNamespace('Package\One\Interfaces'),
            Selector::inNamespace('Package\Two\Interfaces'),
        )
        ->shouldBeInterface();
    }
