smarie/python-pytest-cases: 3.1.2 - Bugfixes with nesting and pytest-asyncio

Now appending fixtures to the closure once it has been built is supported. This fixes an issue with pytest-asyncio. Fixes #176 Fixed issue when parametrize_with_cases was used on case functions themselves (nesting/recursion). This was due to a lack of support of the place_as magic pytest attribute. Fixes #179 Added a warning concerning usage of indirect in parametrize when fixture references are present. See #150 See documentation page for details
