Merge ~cjwatson/lazr.config:rhinectomy into lazr.config:main

Ok, I had to google rhinectomy but I still laughed :)

Hm, coverage is failing for me as 1% is missing. I am pretty sure you ran it, maybe we run a different Python version for coverage? 3.8.10 for me.

Could you please lower the minimum required coverage?

Thank you.

The difference is that src/lazr/config/_config.py:560 is covered when I run the tests but apparently not for you. I'm not quite sure why that would be, but regardless, I've lowered the required percentage slightly for now.

Thanks! Not going down this rabbit hole :-)
