Tools/Matlab: Allow to read LAMMPS output fields

kokkos version of reaxff corrected bond order bugfix from Tomáš Trnka trnka@scm.com posted on lammps-users

Update Kokkos library to v2.6.00

Some output fields have attributes attached on the same
line. e.g. "ITEM: BOX BOUNDS pp pp pp". This patch replaced all
the strcmpi to strncmpi in order to limit the number of character
compared with LAMPPS outputs.
