dependency cleanup; fixes #45 & #48

[rhornb]

This PR fixes a few dependency issues, tests now pass without errors

1. pandera.SchemaModel was deprecated and I replaced it with pandera.DataFrameModel (see https://github.com/unionai-oss/pandera/releases/tag/v0.20.0)

   class LabelFeatureSchema(pa.SchemaModel):

   
   --> this fixed Update to pandera >0.19.3 #45 ; Pandera does not have to be pinned to version < 0.20.0 (but I also didn't pin it to a specific version to make it robust as you mentioned in the issue)
2. Support numpy 2.0 #48 now supports numpy > 2.0

That's awesome, thanks @rhornb !
I'll need to test how this affects running existing classifiers that are saved through the Fractal tasks / manually through Python. My suspicion is that the new version will save classifiers in a way that also requires us using an updated task for them then. If so, we should do that transition synchronized.
