The data bundle contains common GIS datasets like NUTS3 shapes, EEZ shapes,
CORINE Landcover, Natura 2000 and also electricity specific summary statistics
like historic per country yearly totals of hydro generation, GDP and population
data on NUTS3 levels and energy balances.

This rule downloads the data bundle from `zenodo
<https://doi.org/10.5281/zenodo.3517934>`_ and extracts it in the ``data``
sub-directory, such that all files of the bundle are stored in the
``data/bundle`` subdirectory.

**Outputs**

- ``data/bundle``: input data collected from various sources
