Expected behaviour

When cropping, if I set the width and height in the options and disable free crop, then the user should not be able to change the crop window size, only zoom and rotate the image. The aspect ratio of the crop window should not change.

Actual behaviour

The user can change the crop window size. Furthermore, the crop window aspect ratio can be changed by moving the window to the edge of the image and resizing it.

It's worth noting that on Android the crop window and aspect ratio cannot be changed and works as expected. Ideally I would, at least, like to maintain the aspect ratio of crops on multiple images.

Steps to reproduce

1. On iOS, open the cropper with the following options:

   {
     cropping: true,
     freeStyleCropEnabled: false,
     path: image.path,
     width: 200,
     height: 100,
     avoidEmptySpaceAroundImage: true,
   }

2. Change the crop window size to see the first issue.
3. Move the crop window to the edge of the image.
4. Change the size of the crop window while pushed up against the edge to see the aspect ratio issue.
