Calculate the mean deviation of solar orientation of adjacent streets
Orientation of street segment is represented by the orientation of line
connecting first and last point of the segment.
GeoDataFrame containing street network to analyse
>>> streets_df['orient_dev'] = momepy.NeighboringStreetOrientationDeviation(streets_df).series
Series containing resulting values
Series containing used street orientation values
