Consolidate preprocessing workflows of the three extraction pipelines

[VincentVerelst]

There are currently three different extraction pipelines:

• Patch extractions
• Point extractions
• Patch-to-point extractions

For the first two, worldcereal_preprocessed_inputs can be used. This makes sure that the preprocessing is always aligned between these two pipelines.

However, in its current form, worldcereal_preprocessed_inputs cannot be used for the patch-to-point extractions, since Sentinel-1 and Sentinel-2 collections are loaded from STAC instead of from collection and METEO is loaded from Terrascope instead of CDSE.

We need to either unify the preprocessing, or install a safeguard to make sure that the data preprocessing between the three pipelines is always aligned.
