Adding new feature histogram

[omokshyna]

Introduce new feature histogram able to pick up numeric data types across all the features in selected feature list.

Structure similar to VolcanoPlotController

FxModel, FxViewBuilder, FxController, FxUpdateTask

Idea

• reuse HistogramPanel inside a new FxViewBuilder. No need to change HistogramPanel itself too much. Unless you need to set new things. But there is the HistgramPanel.setData method taking a HistogramData instance. Maybe you need to find out how to set the x-axis label (JFreeChart names it DomainAxis)
• Extract all Feature data types from a feature list
• Have user select one data type by ComboBox and then update the HinstogramData

    FeatureList list = ...;
    // this list would go into an ObservableList<NumberType> and be set as items in a combobox - maybe sorted by header name
    List<NumberType> types = list.getFeatureTypes().stream().filter(dt -> dt instanceof NumberType<?>).map(dt -> (NumberType)dt).toList();
    // This selected type would be in model.selectedTypeProperty() and 
    // be bound to the comboBox.getSelectionModel().selectedItemProperty()
    NumberType selectedType = types.getFirst(); 


    double[] data = list.streamFeatures().map(f -> extractDouble(f, selectedType)).filter(Objects::nonNull).mapToDouble(Double::doubleValue).toArray();

  private static Double extractDouble(final ModularFeature f, final NumberType selectedType) {
    Object o = f.get(selectedType);
    if(o instanceof Number num) {
      try {
        return num.doubleValue();
      } catch (Exception ex) {
        return null;
      }
    }
    return null;
  }
