Clean not loaded packages #1245
Description
We have a lot of packages that are not loaded in NewTools.
Some of them are tools that are not finished such as the FlagBrowser.
Some are leftovers and should be removed like NewTools-ObjectCentricBreakpoints.
Some are experiments and we should consider if they should be kept or removed.
Since I'm not sure about what should be kept or not, do not hesitate to comment on this issue with your knowledge.
I'll start by removing NewTools-ObjectCentricBreakpoints that is causing a test failure.
