Subject: [PATCH] Support more modifiers on some terminal emulators

If a terminal emulator supports the kitty protocol, this change will
allow cove to take advantage of this. This means that more modifiers
will work on special keys like enter or escape.

See also this section of the kitty protocol docs:
