Update Stan source to 2.0.0

This merges commit 'e98b409262abd5fcc107101cd2a262b628d19f8b' (tag: v2.0.0)
into feature/arg_refactor.
Catchup to Stan 2.0.0
Remove optimzing with sample_file param test for now
Remove _dict_from_pystanargs and just store a copy of Python version of args

This may introduce some minor differences between the way PyStan and RStan
display the arguments to Stan to the user. All the arguments passed from Python
to Stan are still visible.
Add _dict_from_pystanargs back, alternate workaround for Cython problem
Merge branch 'feature/arg_refactor' into develop
Add enum as a package
Streamline tests
