ConditionalFormattingExpressionRule expression should be escaped

Used version: 0.16.4

I tried to apply a ConditionalFormattingExpressionRule on a range, using the Excel formula:

ws.range(0,0,10,10).style().fillColor(Color.LIGHT_LAUREL_GREEN)
                  .set(new ConditionalFormattingExpressionRule(
                      "MOD(SUMPRODUCT(($A$3:$A3<>$A$2:$A2)+($B$3:$B3<>$B$2:$B2)),2)=0", true
                  ));

But it didnt apply the style. It didn't work until I changed to:

ws.range(0,0,10,10).style().fillColor(Color.LIGHT_LAUREL_GREEN)
                  .set(new ConditionalFormattingExpressionRule(new XmlEscapeHelper().escape("MOD(SUMPRODUCT(($A$3:$A3<>$A$2:$A2)+($B$3:$B3<>$B$2:$B2)),2)=0"), true)));

I think it would be better if the escape would be applied by default in the ConditionalFormattingExpressionRule class, as the use of the library should now have to care about the inner workings of Excel to apply a formula as it is inside Excel.

The relevant part of the formula being the < and > characters, of course.
