Simplify main simulation flow

[FlorianK13]

Right now the process flow of downloading geometries, simulating building, resimulating building is not really good. With the idea of having PV systems as own geometries that are simulated, we should simplify this.

My idea would be to have every geometry stored in the geometries react state with sublists: geometries.background, geometries.simulation, ...

graph TD;
    id1[Click 'Simulation Starten' on Map]-->id2[Load simulation and background buildings to geometry React state];
    id2-->id3[If necessary, load vegetiation to geometry.vegetation react state];
    id3-->id4[Initialize simshady scene with simulation and background geometries, geometries are taken fro react state];
    id5[Click 'Simualte new Building']-->id6[Resort react state of geometries by moving selected building from background to simulationGeometries];
   id6-->id4;
   id7[Create new PV system with its own simulation Geometry]-->id4

Loading

Functions we need:

• initializeGeometries - first search of specific location, download of all relevant geometries
• simulateBuilding - init the simshady scene with relevant geometries taken from geometries react state
• simulatePVSystem - init the simshady scene with geometries from react state and the newly created pv system geometry

I like this approach, one issue I'm seeing here though: When the user clicks simulate new building, how do we avoid re-simulating the previously simulated building(s)?

Random idea: A simulated building could just be a normal building with additional data attached (i.e. the simulated intensities). Then when re-calculating in the react-effect, it's enough to simply simulate those buildings that don't have this additional data attached yet?

Maybe we should have a loadBuildings that just loads all buildings into the scene. Then a simualteBuilding that simulates one building and adds additional info to this building? This function could then be called both at start and at every resimulation.
