MREImagePasteScope class Attachments

Adds image paste to a text field.

It handles the paste shortcut and the on-screen keyboard, adds a "paste image" item to the selection menu, and shows the attached images inside the field when the behavior asks for it. A normal text paste is never replaced: the shortcut pastes text when the clipboard holds text.

MRETextField uses it. Use it yourself to give your own field the same behaviour:

final field = MREImagePasteScope(
  behavior: MREImageCallbackPaste(
    onImagePasted: (image) => upload(image.bytes),
  ),
  builder: (context, hooks) => TextField(
    contentInsertionConfiguration: hooks.contentInsertionConfiguration,
    contextMenuBuilder: hooks.contextMenuBuilder,
  ),
);

With MRENoImagePaste it adds nothing around the field.
