Technical background: when processing the MF6 data, ACER will transform MF6 LAW=7 data into LAW=1 LANG=12 data using an internal ENDF file. The coding for the DLWH block did not loop properly over the transformed data, and as a result generated fully isotropic angular distributions for the secondary particles. The coding for the DLW block on the other hand seems to be correct.
For ENDF/B-VIII.0, only MT16 in n+Be9 is impacted (secondary neutrons and alphas use LAW=7).
Test 72 was added (using ENDF/B-VIII.0 Be9) following the fix.
This resolves issue #188.
