@lkollar,

Before actually doing the release, I'd like to have the following. I'm working on that right now as I don't want to delay musllinux availability.
Please tell me if you disagree.

• libz.so.1 whitelisted (with some symbols blacklisted). feat: add libz.so.1 to whitelisted libraries #334 This would fix libz.so.1.2.3 on CentOS 6 causes repair to segfault #161 & We should probably allow libz linkage, and maybe libexpat #152
• lint the code base a bit more
  • run pyupgrade chore: run pyupgrade --py36-plus #325
  • run isort chore: run isort --py 36 --profile black #328
  • run black chore: run black #329
  • automate previous items with pre-commit chore: add pre-commit for linting #331
• use nox instead of tox chore: move tests from tox to nox #330
• move to an src layout chore: use src layout #332

I have other "housekeeping" improvements on-going but as I don't want to delay musllinux anymore and the list of items required mentioned in the previous comment being completed, I will go on with the 5.0.0 release.
