occurs due to changes in the modelling logic (bug fixes or enhancements), or in
random sampling procedures.

Changes impacting all modules

- |Enhancement| All estimators now recognizes the column names from any dataframe
that adopts the
`DataFrame Interchange Protocol <https://data-apis.org/dataframe-protocol/latest/purpose_and_scope.html>`__.
Dataframes that return a correct representation through `np.asarray(df)` is expected
to work with our estimators and functions.
