Thanks. This is quite nice. A few changes before this can be merged.

1. When a timflow model is solved, the optimal parameters and rmse are printed to the screen. Do this consistent for all notebooks. For example, confined 1 is correct, but confined 4 is not. Use something like

display(cal.parameters.loc[:, ["optimal"]])
print(f"RMSE: {cal.rmse():.3f} m")

2. At the end of most notebooks, a table is shown where the timflow estimated parameters are compared in a table to estimates from other software. This is done with a fancy pandas table. Can you hide the table (hide-input)?
3. Something doesn't go quite right with slugtest 4 on the readthedocs of the PR. Check it out:

Looks nice. Last thing: In the ReadTheDocs, the list on the left side shows the Moensch example as number 2 and there is not number 1 unconfined: https://timflow--73.org.readthedocs.build/en/73/transient/04pumpingtests/index.html. I guess just changing the title of the Notebook will fix that.

Looks great. Thanks for your PR!
