Trying to fix 'Duplicate signature' error from LPD notebook (https://git.xfel.eu/calibration/planning/-/issues/145 ).
This may need updates to other Jupyter/IPython packages, I'm not sure.0
Automated tests in CI, and run xfel-calibrate TEST TEST-CLI --in-folder $PWD/clitest --out-folder $PWD/clitest
manually to check running a notebook.
