-This will bind the option `-i` to the integer `int_option`. On the command line, a single value that can be converted to an integer will be expected. Non-integer results will fail. If that option is not given, CLI11 will not touch the initial value. This allows you to set up defaults by simply setting your value beforehand. If you want CLI11 to display your default value, you can add the optional final argument `true` when you add the option.
