Corrected a typo in the gateff subroutine in thermr (changed 1220 into 1200, see issue #76)
In addition, this update made added the following features and changes:
A small change to the NXS array for continuous energy and photonuclear ACE files (iopt = 1 and 5): in both cases, the isomeric state S, atom number Z and mass number A are now stored in NXS(9), NXS(10) and NXS(11) respectively.
A new input option for acer was introduced for setting the zaid identifier of the continuous energy and photonuclear ACE files (iopt = 1 and 5):
use za in the zaid regardless of the metastable state of the nuclide (default, this is how NJOY has always worked)
use the metastable zaid rules (MCNP 6.3 or lower) in which we use za for ground state nuclides and use za + 300 + s * 100 for metastable nuclides (Am242 and Am242m are exceptions to this rule, for these we use 95642 and 95242 respectively)
