Enable external interrupts on all Maple GPIOs.
Extend the wirish attachInterrupt() and detachInterrupt() interface to
work with all GPIOs.
Note: The STM32 external interrupt lines are multiplexed between GPIO
ports. While any GPIO can be used as an external interrupt, not all of
them can be used at the same time. Each EXTI[n] line selects between
PA[n], PB[n], PC[n], etc. For example, line EXTI5 can be used with STM32
pins PA5, PB5, or PC5, but not all at the same time. See table:
