Backward compatibility notices:

• the syntax of the pair_style snap command has simplified by removing a redundant element specifier.
• the REAX and MEAM packages and their (fortran) library code have been removed. For ReaxFF calculations, there are the pair styles reax/c, reax/c/kk, and reax/c/omp (USER-REAXC, KOKKOS, and USER-OMP package, respectively), and for MEAM calculations there is the USER-MEAMC package, which is fully compatible, and thus pair style meam remains available as an alias to meam/c.
