MixImageOption add rotation functionality

[NicolasDurant]

Hey 👋 awesome project,

would it be possible for you to add optional rotation to the MixImageOption for ImageEditor.editImage()?

I have a use-case where the user first places and rotates an image on top of another, and then I would like to mix them together with your provided blend options. As far as I can see this is not possible yet, right?
