Remove LODI variables in BoundaryConditions.h

In BoundaryConditions.h line 358-362:
Currently, LODI-variables and functions in BoundaryConditions.h float bcLodiDensity{ 0.0f }; float bcLodiVelocityX1{ 0.0f }; float bcLodiVelocityX2{ 0.0f }; float bcLodiVelocityX3{ 0.0f }; float bcLodiLentgh{ 0.0f }; istn't used. But variables take up memory space. It needs to adjust MPIIOCoProcessors after removing variables.
