fixes crash when using contourf with extend option and changing contourf levels to represent a range. #16

Closed nzahasan closed 4 years ago

Using contourf_to_geojson_overlap with extend="both" in matplotlib contourf causes crash because this creates n+1 contour levels thus for last polygon no level existes in countourf.levels list. Also in case of coutourf plot the colors represent range. According to matplotlib documentation if defined levels are [1,5] then this will produce one filled contour with 1<fill_color <=5 level. If used with extend="max" the contour levels will be <=1, >1 to <=5, >5. This pull request tries to fix this issue.

@nzahasan Thanks for the fix. I just created a new release (v0.4.0) that contains it.
