Update DeepRacer Log Analysis.ipynb

Made the following changes to cell 19 in the DeepRacer loganalysis.ipynb

# Use Shapely to generate lines for the inner
# and outer track borders, and centerline
l_center_line = LineString(waypoints[:,0:2])
l_inner_border = LineString(waypoints[:,2:4])
l_outer_border = LineString(waypoints[:,4:6])

# Create a shapely Polygon representing the track
road_poly = Polygon(np.vstack((l_outer_border.coords, np.flipud(l_inner_border.coords))))
road_poly
