How is possible use LiiImagineBundle for private image files

Nobody has claimed this yet.

In my Symfony application, user can upload images but images are stored in non public directory, in my case I store this in /var/card-upload. For display images in templateI use this controller method with
```
fileServe($card->getImage());
}
/**
* Returns a private file for display.
*
* @param string $path
* @return BinaryFileResponse
*/
private function fileServe(string $path): BinaryFileResponse
{
$absolutePath = $this->getParameter('card_directory') . '/' . $path;

return new BinaryFileResponse($absolutePath);
}
}
```
Now I dont how I can this BinaryFileResponse filter by using LiipImagineBundle. It is posiible?

Start with the ServePrivateImageController and its privateImageServe method, then review how BinaryFileResponse serves files from /var/card-upload. Determine how LiipImagineBundle should transform a private image while preserving access control, and consider the request complete when the transformed image can be displayed from the private directory.
