Make MiddlewareFactory replaceable about mezzio

[boesing]

Actually, this factory might become final in one of the next versions while adding an Interface to it.

Would you be open for a Pull-Request where you create an MiddlewareFactoryInterface which implements those public methods which can be found in the current implementation?
We could then change the consumer of this factory (Application#__construct) to use the new MiddlewareFactoryInterface while also registering that interface to the PSR-11 container.

In the end, you can provide your own MiddlewareFactory instead of extending the current one.

So when finished, you end up decorating the current MiddlewareFactory and you can provide your very own logic without depending on the concrete implementation of mezzio/mezzio.

---

This could be the solution for your project then:

namespace Example;

use Mezzio\MiddlewareFactory;
use Mezzio\MiddlewareFactoryInterface;

final class ProjectSpecificMiddlewareFactoryDecorator implements MiddlewareFactoryInterface
{
     public function __construct(
       private readonly MiddlewareFactoryInterface $mezzioMiddlewareFactory
     )
     {
     }

     // implement methods and proxy to mezzio middleware factory when needed
}

Hi, using an interface approach is totally fine for me :)
