Reverted Commit because it did not build

@SCiarella I reverted commit https://github.com/GEMDAT-repos/gemdat-notebooks/commit/10a0d0f22197ca3611bc897b03dc7174bc779bba which has an error while building (also on read the docs):

See error at https://readthedocs.org/projects/gemdat/builds/23121060/ or below:
