Add Python 3.8 compatibility

[d33bs]

Description

This PR adds compatibility for coSMicQC with Python 3.8. To do this, I had to use custom markers as the latest versions of Scipy and Pandas are no longer compatible with Python 3.8. While I was doing this work, I also updated other existing dependencies (which will show in the lockfile).

Thanks for any feedback you may have!

Closes #18

LGTM! 🎉 We will keep the plan to remove after it is "expired".

Thanks @jenna-tomkinson ! Agreed - we'll follow up sometime near October 2024 to update the project for 3.8 end-of-life via #19 .
