User Warnings When Using Smoothed Centerline
User warning if smoothed coordinates need to use interpolate_n_centerpoints (useful for narrow rivers with sparse data)
Example Error: WARNING: Partially invalid smoothed centerline due to sparse centerline data (6 points lie outside the polygon), fix recommendation: rerun riverCenterline to create river object with interpolate_n_centerpoints set to 62+
Include new centerline-width logo
