How to use the xskillscore.crps_quadrature function in xskillscore

Args:
        forecast (xr.object): Forecast with ``member`` dim.
        cdf_or_dist (callable or scipy.stats.distribution): Function which returns the
            cumulative density of the forecast distribution at value x.
        xmin (float): Lower bounds for integration.
        xmax (float): Upper bounds for integration.
        tol (float, optional): The desired accuracy of the CRPS. Larger values will
                               speed up integration. If ``tol`` is set to ``None``,
                               bounds errors or integration tolerance errors will be
                               ignored.
