[SLD] allow to plot with list of voltage levels

[gautierbureau]

Describe the current behavior

When plotting more than one voltage level, one needs to plot all the voltage levels of the corresponding substation(s).

SingleLineDiagram.drawMultiSubstations(network, substationIdList, svgFile);

and the underlying graph:

ZoneGraph.create(substationIdList);

Describe the expected behavior

SingleLineDiagram.drawMultiVoltageLevels(network, voltageLevelIdList, svgFile);

and the underlying graph:

ZoneGraph.create(voltageLevelIdList);
