Author: James Devine
microbit-dal: Added events to MicroBitPin
Added rise, fall, pulse HI and LO events.
The pulse Hi and LO event timestamp given in the MicroBitEvent is the
duration for which the input was HI or LO for.
eventOn(int eventType) is used to configure the events generated
from the pin instance.
