Crossterm 0.29 introduced methods to easily check / extract the event type. E.g. as_key_press_event() and is_key_press(). This commit updates the examples to use these methods instead of matching on the event type. This makes the code cleaner and easier to read. Also does a general cleanup of the event handling code in the examples.
