Added lbm-mesa_pd coupling to have a fluid-particle coupling to the new rigid particle dynamics simulations

as this class is often needed it is now part of the mesa_pd core

To break unneeded dependencies in postprocessing the SQLite part is
moved to its own module and namespace.
Therefore in the include and the function calls
"postprocessing" hast to be removed or replaced by "sqlite" e.g.:
#include "postprocessing/sqlite/SQLite.h" ->
#include "sqlite/SQLite.h"

postprocessing::store... -> sqlite::store...

there is no need for a special rotation matrix class

BlockForestDomain is now passed via argument rather than
recreated in every call.
