Fix for Intervention Image v3

[agskitkat]

Thank you for your work. This is my favorite admin panel for Laravel. On the last project I noticed that $form->image() uses the second version of Intervention Image. I suggest a fix for switching to the third Intervention Image version in the file \src\Form\Field\Traits\ImageField.php:

  
  namespace OpenAdmin\Admin\Form\Field\Traits;
  
  use Illuminate\Support\Str;
  use Intervention\Image\Constraint;
  use Intervention\Image\Facades\Image as InterventionImage;
  use Intervention\Image\ImageManagerStatic;
  // Use class
  use Intervention\Image\ImageManager; 
  use Symfony\Component\HttpFoundation\File\UploadedFile;
  
  ...

  public function callInterventionMethods($target)
      {
          if (!empty($this->interventionCalls)) {
              // Add condition
              if(!class_exists(ImageManager::class)) {
                  $image = ImageManagerStatic::make($target);
              } else {
                  $driver = config("image.driver");
                  $manager = new ImageManager(new $driver());
                  $image = $manager->read($target);
              }
              foreach ($this->interventionCalls as $call) {
                  call_user_func_array(
                      [$image, $call['method']],
                      $call['arguments']
                  )->save($target);
              }
          }
  
          return $target;
      }

 ...

  public function __call($method, $arguments)
      {
          if (static::hasMacro($method)) {
              return $this;
          }
          // Change condition
          if (!class_exists(ImageManagerStatic::class) && !class_exists(ImageManager::class)) {
              throw new \Exception('To use image handling and manipulation, please install [intervention/image] first.');
          }
  
          $this->interventionCalls[] = [
              'method'    => $method,
              'arguments' => $arguments,
          ];
  
          return $this;
      }

As far as I can tell, the methods in version 3 are the same.
