###	Processing steps:

    1.  Download shapefiles from https://doi.org/10.26179/5dc8db48eb58e and file in cwd/input
        
    2.  Run 02_create_single_gpkg.py from cwd
        * Recursively find all shapefiles in cwd/input
        * Group features by geometry type into point_layers, line_layers and polygon_layers
        * Add a source field containing the original shapefile name
        * Drop redundant fields defined in DROP_FIELDS
        * Merge differing attribute schemas, retaining union of fields
        * Save in EPSG:3031 to cwd/output/Antarctica_human_footprint.gpkg
