pip install requires cython but cython is defined in requirements.py. the order of installation should change

[a-fa]

in setup.py it first imports the cython to manage the installation of extension, which may not exist.

we need a workaround so cython is installed upon calling the pip install, then it is used in installing ioniq.

from Cython.Distutils import build_ext
      ModuleNotFoundError: No module named 'Cython'
