Fixes related to the python version of wax

These changes resulted when I tried to bump wax version in clive in clive!218 (merged) and couldn't do it.

• Fix for wheel deploy job
• Get rid of unnecessary runtime dependencies (like cython used for build, pytest used in dev deps for testing)
• related with above - create a separate job anchor runtime_like_python_env which is used for test_wax_python_examples and test_importing_wax` jobs - since this is the real scenario, because users will only install the wheel and not wax dev dependencies.
