open images from clipboard

[nvkomata]

could satty access the clipboard and annotate the latest image? would be more useful for people using gnome shell's screenshot and the like, because it can't be invoked using a command

this would also be faster than opening images in satty using a file manager

alternatively?: otherwise it would be great if satty could be opened on it's own without a file and then have an image pasted into it by the user
