Share of enriched pixels

[vwvbrand]

Once the enriched output dataset is successfully created, it is important to know the share of enriched pixels.
It can be performed through simple NumPy calculation (we should avoid GDAL raster calculator), similar to this:
lulc_upd - initial_lulc
Then, the share of enriched pixels will be:
1-(zero_pixel_count+no_data_pixel_count/total_pixel_count)
