Implement MPIEvaluator for multi-node HPC systems support

Adds a new MPIEvaluator to the EMAworkbench, enabling experiments to be executed on multi-node High-Performance Computing (HPC) systems leveraging the mpi4py library. This evaluator optimizes performance for distributed computing environments by parallelizing experiments across multiple nodes and processors.

Changes include:
- Definition of the MPIEvaluator class.
- Initialization function to set up the global ExperimentRunner for worker processes.
- Proper handling to pack and unpack experiments for efficient data transfer between nodes.

Note: This addition requires the mpi4py package only when the MPIEvaluator is explicitly used, preventing unnecessary dependencies for users not requiring this feature.
