add stub library for backward compatibility (#137)

Browse Source 
* remove legacy to_simple_string and prefer streaming in test code

* driveby fix to clean up self-assign compiler warnings in test code

* driveby fix to clean up unused variable compiler warnings in test code

* another update for issue #123 (constexpr) to allow time_duration constexpr to work

* final updates to make date_time free of library - issue #134

* make a stub library for backward compatibility of libs that link date_time library
