[libtiff] Validate refblackwhite values
The td_refblackwhite value is currently assigned without validation. This may pose an issue as the image can specify the value as nan. This will cause problems later when we use the nan in calcluations. This CL validates each of the float values are not nan and if they are sets them to the default provided by the TIFF spec v6.
