Changed rf.add() and rf.phase() to allow for uint32_t durations 

Instead of limiting number of ticks to 15-bits (32767), RFControl allows for tick size to be any 32-bit number.  If ticks > 32767, RFControl adds repeated LOW or HIGH phases as needed to match full duration.  This provides for much more flexibility in creating pulse trains that include very long-duration "spaces" between repeats.
