Missing "stop" function in the "Simulation" pybind binding

When using dpsim with the python interface, there is an option to do simulations in steps.

After using Simulation.start() to initiate the simulation and Simulation.step() in a loop to calculate the intermediate results, the Simulation.stop() method is called, but it does not exist and raises an exception.

One would expect this function present in the Simulation class

dpsim/dpsim/include/dpsim/Simulation.h

Line 215 in 97f8e1f

void stop();

to also be in the mapping class

dpsim/dpsim/src/pybind/main.cpp

Line 79 in 97f8e1f

py::class_<DPsim::Simulation>(m, "Simulation")

but is not.

This is now being used in a project context with jupyterlab, so it would be nice if we could have the changes also released in PyPI (to enable installation in an easy way).

PR #247 proposes a solution that solves the issue, thanks to @martinmoraga for the hints on how to tackle the problem.
