记录一次抓取万年历的天干地支，生肖和农历月份

由于运营部需求，需要将大量的名人信息进行统计，除了统计姓名和出生年月外，还需要统计与生日日期（阳历）相对应的天干地支，生肖，以及对应的农历月份。刚开始50个，由于量不大，部门每人分配几个轻松搞定。十分钟过后，150个，二十分钟后350个。。。再平均分配每人去统计，此时本人是千万只***在心中奔腾而过，如果需要统计成千上万个名人的话， 每个人什么事不用干，专门坐在电脑前百度算了，无疑是浪费时间和精力，而且还耽误工作。不管是软件设计还是代码编写的时候，有一条规则DRY（Don’t Repeat Yourself），能重复，反复的东西就有方法去代替。况且只要动动脑，方法总比困难多。

抓取天干地支，生肖和农历月份输出CSV类（可扩展）

测试

//测试
$dates = [
    '2008-08-08',
    '2019-09-27',
];
$builder = new Wnl($dates);
$builder->getBranchCsv();

结果

嗯，基本满足需求，如需别的数据，可做相应的扩展
