ds3232 clock frequency calibration via aging offset register #23

It is possible to achieve even more accuracy in timekeeping on ds3232 and it looks like it fair for ds3231 too.

Version 6.4.0 released.

Added agingGet and agingSet functions in order to control aging value on DS323X RTCs.

You can see its usage here: https://github.com/Naguissa/uRTCLib/blob/master/examples/uRTCLib_example_full/uRTCLib_example_full.ino#L64
