[shntnu]

Include parameter spherize_epsilon in

pycytominer/pycytominer/normalize.py

Line 75 in 8ee8a88

scaler = Spherize(center=spherize_center, method=spherize_method)

will become

scaler=Spherize(center=spherize_center, method=spherize_method, epsilion=spherize_epsilon)

and that's pretty much it.

We needn't add a test when adding this, but we should test Spherize #127
