Bug fix regarding the interface condition at a solid wall. Is here implemented only for BB without delay

adds outflow BC in concrete jet setup

add limiter in kernel for Binhgham fluid;
add setup for concrete extrusion

- renamed the mpi module to parallel
- removed the communicationRoutine interface from gpu. gpu now also uses the communicator interface from parallel
- added missing functionality in parallel/Communicator
- moved ws2_32 library dependency on windows from VirtualFluids_GPU to parallel

Bug fixes in sharp interface, Liquid phase now also initialized like gas phase in attempt to balance distruction of momentum with generation of momentum.

Implements immersed boundary in sharp interface kernel / Implements using of LIGGGHTS domain decomposition for parallelization / fixes performance issue für LiggghtsCouplingSimulationObserver
