Filling Range Gaps (#724)

error occured loading gpkg file containing polygons same file worked fine with previous versions of fiona failure points to this pyx file extending the ranges to have no gaps would stop error being raised and allow code to run. modulo would be 0 returning unknown rather than unsupported.
