Variables in product file have NaN instead of fill value #118

Closed mhidas closed 2 years ago

In the velocity hourly files we have, e.g. 

        float UCUR(OBSERVATION) ;
                UCUR:_FillValue = 99999.f ;

However, ncdump shows that the variable can have NaNf values. These should be replaced with the specified fill value.

I've just noticed this in the velocity hourly product, as at commit 0e067eb5477c028c8cbc94d5e37e5b9367ab3dea. Haven't checked if this is also an issue in the other products.

Also occurs in the aggregated_timeseries product, e.g. the file generated by the unit test.

This also leads to some global attributes being NaN, e.g. 

        :geospatial_vertical_max = NaNf ;
        :geospatial_vertical_min = NaNf ;
