Input parsing

In order to simplify input parsing, you can use the Symfony Serializer component to
automatically denormalize parsed request body or get params to a data transfer object
of your choice. In your controller, simply mark one of the parameters with #[Payload]
attribute and typehint it with your desired class:

public function __invoke(#[WonderNetwork\SlimKernel\Http\Serializer\Payload] MyDto $input) {}

If the serializer fails to denormalize the input, a HttpBadRequestException will be
thrown with a semi-helpful message attached. If you require custom serializer setup,
you can register your own instance using the following container key:

\WonderNetwork\SlimKernel\ServiceFactory\SlimServiceFactory::INPUT_DENORMALIZER
