Start the cropper with cropdata

[Matthijz98]

I want to mount the cropper with the crop settings that the users saved before.
The crop results are saved and returned by my api.

But the crop property only accepts x and y not height and width.

Expected behavior
The crop property can accept a value like this:

{"width": 2617, "height": 2617, "x": 848, "y": 568}

The cropper uses these values as the start values

I think that what you are looking for is the same as the initialCroppedAreaPercentages/initialCroppedAreaPixels of react-easy-crop.
If you are interested to contribute this feature, feel free to check the React implementation and port it to the Svelte one. I'd be happy to review the PR 🙂
