compatibility with older numpy version

[JoshuaHesse]

Hi,

I am trying to use your Datascope package but due my project' setup I am required to use numpy version 1.19.2 - is there any way make that work ? I have tried a couple of approaches but the shapley_cy file keeps creating the following error:
ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 96 from C header, got 80 from PyObject

thank you for your help!
