Incompatibility with scipy 1.9.0
The experimental dependencies CI workflow has started failing because the hanning window was removed in SciPY 1.9.0, see https://scipy.github.io/devdocs/release.1.9.0.html#expired-deprecations:
__ ERROR at setup of TestCliQtransform.test_filter_timeseries[highpass-filt0] __

def get_window(window, Nx, fftbins=True):
"""
Return a window of a given length and type.
Parameters
----------
window : string, float, or tuple
The type of window to create. See below for more details.
Nx : int
The number of samples in the window.
fftbins : bool, optional
If True (default), create a "periodic" window, ready to use with
`ifftshift` and be multiplied by the result of an FFT (see also
:func:`~scipy.fft.fftfreq`).
If False, create a "symmetric" window, for use in filter design.
Returns
-------
get_window : ndarray
Returns a window of length `Nx` and type `window`
