Transfer of MPI parallelization into operators:
===============================================
As was already the case with the `MetricGaussianKL_MPI` in NIFTy5, MPI
parallelization in NIFTy6 is handled by specialized MPI-enabled operators.
They are accessible via the `nifty6.mpi` namespace, from which they can be
imported directly: `from nifty6.mpi import MPIenabledOperator`.
