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: EXTI Line Maple Pin STM32 Pin 0 D2 PA0 0 D27 PB0 0 D15 PC0 1 D3 PA1 1 D28 PB1 1 D16 PC1 2 D1 PA2 2 D17 PC2 2 D25 PD2 3 D0 PA3 3 D18 PC3 4 D10 PA4 4 D19 PC4 5 D13 PA5 5 D4 PB5 5 D20 PC5 6 D12 PA6 6 D5 PB6 6 D35 PC6 7 D11 PA7 7 D9 PB7 7 D36 PC7 8 D6 PA8 8 D14 PB8 8 D37 PC8 9 D7 PA9 9 D24 PB9 9 D38 PC9 (BUT) 10 D8 PA10 10 D29 PB10 10 D26 PC10 11 D30 PB11 12 D31 PB12 13 D32 PB13 13 D21 PC13 14 D33 PB14 14 D22 PC14 15 D34 PB15 15 D23 PC15
