Improvement: URL based image manipulation with parameters

[cord]

Would be great if the package supports flexible resizing, effects etc. through url parameters. This can "almost" be done, but the image cache does not support this:

In short:

Issue: ImageCache does not support url parameters, but takes only filename as cache key

possible solutions:

• allow to configure custom implementation of ImageCache
• allow to pass cache key parameters through applyFilter() method

---

working example for 'dynamic' filter:

    public function applyFilter(Image $image)
    {

        // issue:
        // parameter is not added to cachekey

        // w = width in px
        $width =request()->input('w');
        $quality =request()->input('q') ?? 90;

        $image->resize($width, null, function ($constraint) {
            $constraint->aspectRatio();
        })
            ->encode('jpg', $quality)
        ;
        return $image;
    }

example requests:

1. generate thumbnail:

http://yourhost.com/{route-name}/original/{file-name}?w=100&q=50

2. generate preview:

http://yourhost.com/{route-name}/original/{file-name}?w=200&q=90

both urls will return the same cached image (whichever was called first) as the cache key does not support parameters.
