Copy Text from Image

[iainx]

Add a button to the media edit view that uses VisionKit to analyse the image and use any text found as the image description.

It doesn't use the live text feature for two reasons

• it isn't supported in SwiftUI's Image and using a UIImageView in the place of the Image didn't work easily to match the current design
• the image could be scaled such that the text was so tiny it was unreadable and unselectable

With these reasons I thought just adding a second button was the easiest option.
