install_requires incomplete?

I see that in your CI workflow, you install a few more things than what is declared in your setup.py. Are they really needed? If so, they should be declared as install_requires or as optional dependencies in setup.py. Also see #47

Ah, also I found this documentation that suggests setup.py declarations are indeed incomplete: https://pyautogalaxy.readthedocs.io/en/latest/installation/overview.html#dependencies and https://pyautogalaxy.readthedocs.io/en/latest/installation/source.html#building-from-source
