[alibaba/easyexcel]03格式公式类型单元格无法获取DataFormatData

03格式excel，单元格为公式，并设置单元格格式为数值，2位小数。

触发Bug的代码

   public class XLSBigDecimalConverter implements Converter<BigDecimal> {

    public Class<?> supportJavaTypeKey() {
        return BigDecimal.class;
    }

    public CellDataTypeEnum supportExcelTypeKey() {
        return CellDataTypeEnum.NUMBER;
    }

    public BigDecimal convertToJavaData(ReadCellData<?> cellData, ExcelContentProperty contentProperty, GlobalConfiguration globalConfiguration) throws Exception {
        BigDecimal val = cellData.getNumberValue();

        if (cellData.getDataFormatData() != null) {
            String format = cellData.getDataFormatData().getFormat();
            System.out.println(format);           
         }
        return val;
    }

    public WriteCellData<?> convertToExcelData(BigDecimal value, ExcelContentProperty contentProperty, GlobalConfiguration globalConfiguration) throws Exception {
        return null;
    }

}

cellData.getDataFormatData() 为空。代码错误应该在 FormulaRecordHandler 没有将DataFormat设置给tempCellData
