Detailed Description
an algorithm that unpacks NetCDF packed values
Applies a data transform according to the NetCDF attribute conventions for packed data values. https://www.unidata.ucar.edu/software/netcdf/docs/attribute_conventions.html
Variables in the input dataset are scanned for the presence of the scale_factor and add_offset attributes. When both are present an element wise transformation is applied such that
out[i] = scale_factor * in[i] + add_offset
The input array is expected to be an integer type while the type of the output array may be either float or double. Valid value masks may be necessary for correct results, see teca_valid_value_mask.
