Do something after screenshot

[barraIhsan]

Is it possible when screenshotting (either with s, S and <C-S> on a default bind) it will:

1. Save the file (default behaviour) and follow screenshot settings such as --screenshot-template
2. Copy the screenshot to the clipboard so we can directly paste it somewhere (e.g. Discord)
3. Apply custom extended attribute to the file (e.g. apply user.xdg.tags), or if it's simply not possible can we just run a command (like after-screenshot hook or smthing like that) so we can do setfattr using the cli
