openap 1.3 is not compatible with scipy 1.13 (latest stable release)

[nhuet]

When trying to import openap, we get:

/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/openap/__init__.py:3: in <module>
    from .extra import filters
/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/openap/extra/filters.py:3: in <module>
    from scipy.signal import gaussian

It seems that gaussian must now be imported from scipy.signal.windows.
