Clipboard not fully working for Wayland

[cmprmsd]

Hey, great tool!

There is com.github.phase1geo.annotator --use-clipboard in order to get an image from clipboard and edit it directly. This method does not work on Wayland. Also wl-paste | com.github.phase1geo.annotator won't work as there is no flag for stdin.

When you open Annotator and paste an image it will be opened in the editor. However, this is one step that could be skipped.

Also the way how image pasting works, while working on an annotation is quite disturbing. E.g. I annotate an image with 20+ elements and accidentally press ctrl+v. All work is gone, as the revert button does not revert paste but the changes within the editor. This might be worth another issue though.

Keep up the good work!
