fails to build with sundials 7

[drew-parsons]

sundials 7 has been recently released, and requires some code updates in dyssol.

One thing to note is that MPI support (when enabled) is now in sundials core, not only in the sundials parallel components, because of SUNComm. When building dyssol against MPI-enabled sundials 7, there will be a compilation error via sundials_matrix.h included in DAESolver.h, sundials_types.h:57:10: fatal error: mpi.h: No such file or directory. This can be easily worked around by using mpi compilers, CXX=mpicxx

Then, ida_impl.h is no longer provided in /usr/include/ida, so

Thirdly, realtype does not get defined
