Group specific error pages and prefix error pages

[mertgibi]

I tried my best to do. I would be very happy if I could contribute.
I did the question I asked today and a little more.

I added the following features;

Error pages created in groups are now specific to that group

$router->group('/test', function ($router) {
    $router->get('/',function () use ($router) {
        return 'text page';
    });
    $router->get('/blue',function () {
       echo 'blue page';
    });
    $router->group('/testing', function ($rou) {
        $rou->get('/',function () {
            echo 'testing page';
        });
        $rou->error(function () {
            echo 'testing error page';
        });
    });


    $router->error(function () {
        echo 'test error page';
    });
});

'home@notfound' is now available in error function

$router->error('home@notfound');

route prefix can be set in error function regardless of group

$router->error('home@notfound',['prefix' => '/test']);

That's all,
maybe it could have been better. That's as much as I can. I really need this feature

i tested it again with the last edits and it doesn't seem to be a problem. i've an idea to create custom pages based on error codes. i'll work on it.

idea;

$router->error('home@notfound',['errorCode' => 403]);
