Determine availability matrix

The script performs a land eligibility analysis of what share of land is availability for developing the selected technology at each cutout grid cell. The script uses the atlite <https://github.com/pypsa/atlite>_ library and several GIS datasets like the Copernicus land use data, GEBCO bathymetry data.

Natural reserves are from https://zenodo.org/records/14875797

The copernicus land monitoring data is/can be fetched by the pipeline. The GEBCO data is stored in the PyPSA-China-PIK zenodo bundle or must be manually downloaded from the General Bathymetric Chart of the Oceans (GEBCO) <https://www.gebco.net/data_and_products/gridded_bathymetry_data/>_.
