Unfortunately with gcc-13.2.1 with optimizations there is a warning, which I was not able to correct.

Other compilers gcc-14, clang-17 and 18, msvc had no problems with the
former code.

... scheme. Passing a vector of vectors (outer for processes,
inner over the process variables) of residuum names for each
process variable.

This is mostly copy from the VectorMatrixAssembler.

A little bit :) 0.5% maybe. Measured on TRM/Mockup ctest.

This costs some memory (now element ids and local assembler references are stored)
but simplifies the code. If local assemblers would return an element id,
the code could be simplified further.

This slightly simplifies code avoiding extra boolean variable.

This is not sufficient for the staggered scheme yet.

Same as 3e9a70cd but for global matrices.

A little code duplication in favor not to deal with pointers.

Same fix as in ogs/ogs!4865

Allows co-existance with ogstools python package in build dir virtual environment.

Requires to uninstall ogs wheel in venv and to set the PYTHONPATH (both handled by CMake and .envrc-file used by the direnv-tool).

ogs.simulator works in wheel only

CLI flags without additional value can now be given with e.g.:

cli.GMSH2OGS(gmsh2_physical_id=True) # or gmsh2_physical_id=None

cli.GMSH2OGS(gmsh2_physical_id=False) # disables the flag.
