Bootstrap python tests (#697)

* move current integration tests to the integration folder

* move pyscript.py into its own python folder

* change the path for python unit testing files

* change pyscript.py path

* Update Makefile

* remove echo

* replace conda run with pytest directly

* oops, add python test files I embarrassingly forgot to add
