KeyCode Parentheses support

I need parenthese support for my program;
KeyCode:: ParenLeft,
KeyCode::ParenRight,

Iced seem to not support these Keys at the moment. This is Kinda wierd at this point since those are quite common and usefull.

They are supported. They produce a KeyPressed event where text is Some("(") (or ")") or, if you prefer to detect the actual key, it would be Key::Character("9") (or "0") with Modifiers::SHIFT being pressed. The second option depends on the keyboard layout.
