Unsigned byte data should be written with unsigned data type #3

Files are written in NetCDF4 and this version supports unsigned data types. Beside using the _Unsigned attribute the data should be written as unsigned data. http://www.unidata.ucar.edu/software/netcdf/docs/BestPractices.html#bp_Unsigned-Data

The current netcdf library version (4.3.22) we use does not allow it. Probably we need to update to 4.6 or higher.

To my understanding, the _Unsigned attribute is only used for (NetCDF3) signed integer data types.
