Support for Kitty multiple-cursors protocol

Hello

This thread is just to share a new initiative from Kitty's author, who has come up with a new protocol to express multiple cursors at the terminal via escape codes:

(mawww is already tagged in it.)

I know my precedent thread was already Kitty related, and I apologize. I'm not trying to oversell this terminal to anyone, it's the just the one I'm currently using and I like that it tries to push the boundaries of what's possible for TUI apps.
