Clean up ancillary script

Clean up of ancillary scripts.

[kobebryant432]

Ancillary scripts are not package relevant - although extremely usefull. The code for these should be moved to another repository as they have no direct influence on Valenspy or how it is used.

Where should this be placed? Options:

1. A new CORDEX.be II repo
2. Storage for climate repo
3. An RMI git-lab repo

Code including preprocessing of CLIMATE_GRID & radclim.
@Ivanderkelen what would you suggest, as these are mainly your scripts.

[Ivanderkelen]

Agreed. The scripts I created are already saved in other locations:

• preprocess_CLIMATE_GRID: https://github.com/Ivanderkelen/CLIMATE_GRID_processor (personal repo)
• preprocess_era5: https://github.com/VUB-HYDR/storage4climate/tree/main/download_scripts_era5

These two can thus be removed in the Valenpsy repo.
Left are:

• convert_CORDEX_excel_to_yaml: can this be integrated in the Valenspy source code somehow? as it would be part of the package, as CORDEX variables are key? Other opinions welcome. Maybe we don't need to keep the script at all.
• preprocess_radclim: make separate repo, eg RMI git-lab?

Note that there is already a storage4climate repo that I mainly maintain: https://github.com/VUB-HYDR/storage4climate/
