pyerrors does not work with the upcoming numpy 2 release

pyerrors raises multiple errors in combination with the numpy 2 release candidate

• I fixed the relevant breaking changes in autograd in the following PR Fix numpy v2 breaking changes HIPS/autograd#618
• matplotlib raises ImportError: numpy.core.multiarray failed to import. This should be fixed in the next release.

After the relevant changes have made it to pypi we will probably have to bump our minimal dependencies and potentially drop support for python 3.8 as it does not work with numpy 2 (EOL is 31 Oct 2024).

Thanks a lot for anticipating this and for fixing the problems in the dependencies! I am fine with dropping python 3.8 in the future.
