Serialize SchemaStatisticalVariable to JSON-LD

Implementation

      'measurementDenominator': convertToJsonLd(
          measurementDenominator, [SchemaStatisticalVariable]),
      'measurementMethod': convertToJsonLd(measurementMethod,
          [SchemaDefinedTerm, SchemaMeasurementMethodEnum, String]),
      'measurementQualifier':
