pyproject: add config file
This will tell pip et al to call our setup.py for the majority of
packaging concerns, but also gives us a place to put standard config
stuff like black.
This was previously D9833, but was rolled back due to test
breakage. nbjoerg thinks that breakage is now resolved, so we're
trying again.

Check data can be written/read from sidedata

Check upgrade behavior
======================
Right now, sidedata has not upgrade support
Check that we can upgrade to sidedata
