Hexagon: updated software/libraries

Hexagon has updated software and libraries.

IMPORTANT: The new MPI, cray-mpich 6.0.0, is based on MPICH3 and is NOT binary compatible with version 5.x which is based on MPICH2. Therefore all parts/libraries used in your code needs to be compiled with the same MPI version (either 5.x or 6.x). Similarly, to use the latest installed version of e.g. netcdf libraries you must use MPI 6.x.

See http://docs.cray.com/books/S-9407-1306//S-9407-1306.pdf for full information.
