Incorporate changes from workalendar 3.2.1:

- Added DEEPAVALI days for 2019 and 2020, thx @pvalenti (#282).
- Fixed Germany Reformation Day miscalculation. Some German states include Reformation Day since the "beginning" ; in 2017, all states included Reformation Day as a holiday (500th anniversary of the Reformation) ; starting of 2018, 4 states added Reformation Day (#295).

Incorporate changes from workalendar 3.2.0:

- Removed dependency to `PyEphem`. This package was the "Python2-compatible" library to deal with the xephem system library. Now it's obsolete, so you don't need this dual-dependency handling, because `ephem` is compatible with Python 2 & Python 3 (#296).
- Raise an exception when trying to use unsupported date/datetime types. Workalendar now only supports stdlib `date` & `datetime` (sub)types. See the `basic documentation <https://workalendar.github.io/workalendar/basic.html#standard-datetime-types-only-please>`_ for more details (#294).
