calculate_relevance_table() does not work with y in form of numpy.ndarray

[nicolasj92]

The problem:
The function feature_selection.relevance.calculate_relevance_table() is supposed to support numpy.ndarray as y argument. This causes an attribute error though because numpy.ndarray does not have the sort_index function that is called in line 164 of https://github.com/blue-yonder/tsfresh/blob/main/tsfresh/feature_selection/relevance.py

Anything else we need to know?:
