Function reverse_scaleoffset 

pub fn reverse_scaleoffset(
    data: &[u8],
    cd_values: &[u32],
) -> FormatResult<Vec<u8>>

Reverse the HDF5 scale-offset filter (decompress only).

cd_values follows H5Zscaleoffset.c’s 20-entry schema. The output is the raw element buffer in the dataset datatype’s byte order.
