17 error catching when calculating summary statistics

[bvandekerkhof]

Description

Bugfix when no sources are present in the z_src array. We now account for that in the code and make sure the code does not brake down the line in the plotting.

Fixes #17

Type of change

• Bug fix (non-breaking change which fixes an issue)

Jupyter Notebooks

No changes in notebooks.

How Has This Been Tested?

Tested by running the support_functionspost_processing.calculate_rectangular_statistics(<INPUTS>) and plotting.plot.plot_quantification_results_on_map(<INPUTS>) methods on saved files which both do and do not contain values in z_src.
