Add coordinate system parameters to scenario file
### Problem to solve
At the moment, it is hard to interchange information between Vadere's scenario file and external applications fully automated because some essential information are missing in the scenario file. For instance, the coordinate system which is used by Vadere and if imported data (e.g., from openstreetmap.org by using [osm2vadere](https://gitlab.lrz.de/vadere/vadere/tree/master/Tools/Converters/osm2vadere)) was shifted to the point (0;0) to avoid problems in Vadere when using big coordinates (e.g., 50,000;50,000).
### Further details
The new information about the coordinate system should be add to `topography` section of the scenario file:
```
"topography" : {
"attributes" : {
"bounds" : {
"x" : 0.0,
"y" : 0.0,
"width" : 38.0,
"height" : 12.0
},
"boundingBoxWidth" : 0.5,
"bounded" : true,
/* TODO: Add new information about the coordinate system, e.g.:
* "coorinateSystem": "EPSG:25832",
* "coordinatesShiftedBy": { "x": 10, "y": 10 }
*/
},
```
