How to change default dir cache folder?

```php use Gregwar\Image\Image; $img = new Image(); $img->setCacheDir('customDir')->create($width, $height)->fill($faker->hexcolor)->save($path, config('mime.service')); # expected customDir/a/b/3.... ``` keeps creating `cache/images` folder

\Gregwar\Image\Image::open('assets/images/blabla.webp')->setCacheDir('assets/caches')->guess();
