Delegate PiGpioIsrDelegate
Defines a signature for ISR callbacks. Conatins the pin number, a level change and a microseconds timestamp. The timestamp wraps around every ~72 minutes. Unlike alerts, interrupts are generated with level changes. Make sure you hookup pull-down/pull-up resitors for interrupts to work as they depend on current flowing through the pin in order to fire consistently.
