In NJOY2016.49 GROUPR learned to create MF6 MT18 spec and prod arrays to be stored in the output GENDF file based on issue #118 .
This leads to the situation that the GENDF section MF6 MT18 contains for each group NZ dilution dependent spec and prod values, where MATXSR expected only one value. Consequently, the spec and prod arrays in record 10d of the output file were simply wrong.
This fix lets MATXSR use the dilution dependent value according to the sub-material i.e. the dilution/temperature pair.
