Building dependencies takes 15+ minutes because of Pandas 1.5.3 (and how to fix it) #2425

How to reproduce the problem

I didn't have any errors -- building dependencies took so long I gave up. I noticed it was stuck on compiling pandas, which was at version 1.5.3 because another dependency required pandas < 2.0.0. I fixed the install by setting the minimum pandas version to 2.0.0 in pyproject.toml, and it installed all dependencies within a minute.
