Ugly CGMES DL diagram

  Here is attached sample.zip, a small 1 substation, 3 voltage level CGMES file, extracted from real data. sample.zip

Using automatic layout without extensions and vertical substation layout we can generate this diagram:

The following code generates using same layout configuration a DL file.

Network network = Importers.loadNetwork("sample.zip");

new LayoutToCgmesExtensionsConverter(new VerticalSubstationLayoutFactory(), new PositionVoltageLevelLayoutFactory(new PositionFree()), new LayoutParameters(), true)
    .convertLayout(network);

new CgmesDLExporter(network)
    .exportDLData(new FileDataSource(Paths.get("/tmp"), "sample"));

Then after adding sample_DL.xml to the original zip, we can generate this diagram using CGMES voltage and substation layout:

I seems that there is a lot of missing data and diagram is not really usable.
Did I missed something in the way I generated the data?
Maybe we introduced a regression in last PR?

I'll investigate. However, Importers complains about this sample.zip network (com.powsybl.cgmes.model.CgmesModelException: nominalVoltage not found for ...).
Could it be possible to have a powsybl-working version?

Sorry, I uploaded a new version. Is it better?

thx: no import exceptions, with this one.
