[Feature]: kitty keyboard protocol

Feature description

Please, add support of kitty advanced keyboard input protocol. Some apps like f4, far2l (Linux Far Manager ports) or fish (shell) need it for all key combinations to work properly. As a simpler alternative, win32-input-mode also can be considered, but I am not sure if fish supports it or not (f4 and far2l definitely do).
