Decorator attributes are not properly set

[So-Fras]

Describe the current behavior

In the setDecoratorAttributes method of the DefaultSVGWriter class, the line
List<String> svgNodeSubcomponentStyles = styleProvider.getNodeSubcomponentStyles(graph, node, subComponentName) may call the AbstractVoltageStyleProvider getNodeSubcomponentStyles.

The decorator gets the style of its associated node (a switch node, a feeder node, etc.). This behavior may disturb or bother users.

Moreover, when the node is a FeederNode, the getNodeSubcomponentStyles calls in turn the getSubComponentVoltageLevelInfos method.
That last method was designed for components like two-winding transformers, as the if condition (if (subComponentName.equals(WINDING2))) shows, and not really for decorators.

Describe the expected behavior

In the setDecoratorAttributes method of the DefaultSVGWriter class, a function specific to decorators should be called to retrieve the svgNodeSubComponentStyles, so that the decorator does not end up with the style of its associated node.

Another solution would be to delete this line of code, but this would prevent users from customizing the decorators.
