[alibaba/easyexcel]LongestMatchColumnWidthStyleStrategy Date类型自动列宽不生效

【必现】日期类型的字段自动列宽不生效，源码未对日期类型做处理。

  public class EasyIssueReport {
    public static void main(String[] args) {
        EasyExcel.write(getTestFileOutputStream()).registerWriteHandler(new LongestMatchColumnWidthStyleStrategy())
                .head(Pojo.class)
                .sheet().doWrite(getTestData());
    }

    static List<Pojo> getTestData() {
        List<Pojo> list = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            Pojo data = new Pojo();
            data.setDate(new Date());
            data.setLocalDate(LocalDate.now());
            data.setLocalDateTime(LocalDateTime.now());
            list.add(data);
        }
        return list;
    }

    @Data
    public static class Pojo {
        @ExcelProperty("date")
        Date date;

        @ExcelProperty("localDate")
        LocalDate localDate;

        @ExcelProperty("localDateTime")
        LocalDateTime localDateTime;

        @ExcelProperty("longText")
        String text = "long long long long  long long long text";
