Incorporating two changes to the spectral Granger causality SPI:
Only examining F values for frequencies > 0 rather than >=0.
Flag ignore_NaN that defaults to True, in which case np.nanmean or np.nanmax is used instead of np.mean or np.max.
For #2, also added a catch that if >10% of F values in the given frequency range are NaN, the result will be manually set to NaN in the corresponding directed region pair.
