Workplan 2024: Towards finishing the data recipes

The basic framework for the data recipes is essentially implemented. It contains download functions for the corresponding climatological datasets (ÖKS15, SPARTACUS, ERA5, CORDEX, DestinE), a remapping function and a cutting function. This issue is intended to highlight the final details to be implemented before getting feedback from the community. The final result will be presented in form of a workshop on Klimatag in April 2025.
