This is a complementary function to UvalueEstimations.classify_decile_newvalues, which does not use pandas
so that we can use this function inside of our lamdbas, without having to import pandas.

Classify a list of new values into pre-established deciles.
This function is an alternative to UvalueEstimations.classify_decile_newvalues that does not depend on pandas,
making it suitable for use in environments where pandas may not be available (such as AWS Lambda).
:param decile_boundaries: A list of decile boundaries. These define the ranges of the deciles.
:param decile_labels: A list of labels for the deciles. These are the classifications to be assigned to the values.
:param new_values: A list of new values to be classified into the deciles.
:return: A list of classifications for the new values. Each classification corresponds to the decile in which
the respective new value falls. If a value falls outside the range of the deciles, its classification is
None.
