Added DS3231 Real Time Clock FeatherWing. This extends the DS3231 library and makes updating the time extremely easy by having ability to change individual numbers instead of the entire time/date structure as well as a few other goodies like checking number of days and getting/setting by unix time on boards that support this. At this time, there are some known issues running the unix functions on the nRF52840 Express and Particle Boards.
