Steps to Reproduce

1. run the test case keikai.test/io.keikai.model.ImporterTest.nameIndexOverflow()
check branch https://github.com/zkoss/keikaicml/tree/KEIKAI-432

Current Result

Expected Result

no error

Debug Information

1. it only prints the exception if you configure the logger correctly.
2. root cause

public class NamePtg extends OperandPtg implements WorkbookDependentFormula {
	...
	private int field_1_label_index;
...

	public void write(LittleEndianOutput out) {
		...
		out.writeShort(field_1_label_index);
}

When serializing a NamePtg, it writes an integer into a short and causes the overflow.
