refactor(tests): refactor test framework

* use keepable temporary dirs instead of manually managed temp folder
* use pytest-order and add optional --path arg to update_flopy.py CLI
* remove binary_file_writer.py, disu_util.py, budget_file_compare.py
* rename Simulation -> TestSimulation and Framework -> TestFramework
* partially refactor gwf test scripts with pytest-cases
* remove mfpymake as a testing dependency
