Can't do clean pip install of kaiju

[imedan]

I have run into an issue where it is not possible to install kaiju from a fresh python environment. When doing so, I get the following error:

What seems to fix this is installing coordio first and then trying to install kaiju again. I think the reason this occurs is in setup.py, coordio is in the setup_requires variable:

kaiju/setup.py

Lines 117 to 120 in 2bd0baa

	setup_requires=[
	"sdss-coordio>=1.2.1",
	"pybind11>=2.2.4"
	],

This above issue then also applies to installing mugatu from a clean install, as it depends on both kaiju and coordio, so coordio needs to be installed first before installing mugatu. This isn't a huge deal, the main headache it is causing me now is I can't build the documentation for mugatu as it crashes when the pip install of mugatu fails.

My main question is, is this setup requirement set correctly and/or necessary? For the former, I am wondering why is is failing at this setup requirements step and if there is a fix. If this isn't easily fixed or is necessary, I can also look around for some workarounds on my end.
