Date and Period Utilities

Vectorized helpers for numpy.datetime64 arrays and time periods. The pyinterp.dateutils functions decompose dates without converting them to datetime objects, and Period / PeriodList represent time intervals and collections of them; both modules are available as pyinterp.dateutils and pyinterp.period.
