I'm having a problem with a null pointer exception
java.lang.NullPointerException: Cannot invoke "java.lang.Integer.intValue()" because the return value of "org.dhatim.fastexcel.reader.SimpleXmlReader.getIntAttribute(String)" is null

I've done some investigation and if I look at the code I see the exact problem, it is an auto-casting from Integer to int
it is related to line 85 of class RowSpliterator
int rowIndex = r.getIntAttribute("r");
the getIntAttribute function returns an Integer and this could be null which is the case and of course, it fails when it tries to cast it to an int.
