np.save incorrectly saves System.Byte arrays as signed #461

in function GetDtypeFromType ... if (type == typeof(Byte)) return "|i1"; ... i1 gets translated to signed integer https://numpy.org/doc/stable/user/basics.types.html

Bump. This issue is still existing. I am saving a numpy array (an image) with positive values only using np.save(). Positive values only are verified calling amin() on the array. After reading the file again, the array contains negative values. Is there a workaround for this?
