Remove all usage of python2_3.py (#1939) 
* Remove all usage of python2_3.py

Technically these functions were exported at the top level of the library, this removes them without warning... If we want to we can bring them back for there, but I honestly don't think its needed, as we are py3 only now and have been for multiple releases.

This may introduce a number of 'useless cast' or similar but those were always happening anyway
