alues (that have preferably been computed over
    short windows) that may include a large fraction of contaminated samples.
    The clean EEG is assumed to represent a generalized Gaussian component in
    a mixture with near-arbitrary artifact components. By default, at least
    25% (`min_clean_fraction`) of the data must be clean EEG, and the rest
    can be contaminated. No more than 10% (`max_dropout_fraction`) of the
    data is allowed to come from contaminations that cause lower-than-EEG
