Only use `openeo_classification.resources` package for input resources

While working on #1 I noticed that openeo_classification/resources is mainly used for generated/output files.

I think this should be avoided and openeo_classification.resources should be solely for input resources

df = pd.read_csv("resources/training_data/final_features.csv",index_col=0)
