scipy.integrate.simps renamed

[Julia Wind]

Ran into an issue when trying to use the ica module in my recently created conda environment:
cannot import name 'simps' from 'scipy.integrate'

Cause:
integrate.simps from SciPy was renamed to integrate.simpson. Using integrate.simps is possible for scipy versions <1.11.0, but does not work anymore for newer versions.

Fix:
Should be an easy fix in cellpy.utils.ica
