A new version of the System.Drawing.Common package is released with every major .NET version

Which version should ScottPlot depend on? How often (if ever) should it be changed?

Currently ScottPlot 4.0 depends on 4.7.0 and ScottPlot 4.1 depends on 5.0.0, but these weren't chosen intentionally

Both could be upgraded to the latest (5.0.2) but I'm not sure if this would fix problems or cause more pain

Alternatively I could make it so each build target uses the version-matched System.Drawing.Common
