Index instances obtained from EstimatorDF.feature_names_in_ and TransformerDF.feature_names_out_ are now named "feature" instead of "feature_in" and "feature_out", respectively
Series instances obtained from TransformerDF.feature_names_original_ are now named "feature_original" instead of "feature_in", and their indices are now named "feature" instead of "feature_out"
This is to separate the semantics of the originating property from the column index, which may be used in other contexts.
