ha借助node-red实现工作日判断

ha使用中有时候自动化需要用到工作日判断，可是ha没有自带提供。后来使用了一段时间https://github.com/Crazysiri/chineseholiday/ ，发现有些自定义需求无法满足，也不大会ha中的代码操作，决定自己写一个工作日判断。

大致需求

使用node-red在ha中提供状态
从星期几判断当日是否为工作日
从节日判断当日是否为调休
其他自定义需求后续添加

基本逻辑

前提：

node-red的data文件夹绝对路径：/data 安装方式：docker

如果和我不同，则根据实际情况修改代码中的路径。

先在node-red的data文件夹下创建一个info目录，然后获取今年的假期安排（来源：seimin/holiday-cn），并下载到info文件夹下。

获取节日调休情况，在代码判断后，如果不是节日，则根据当前星期几判断是否工作。

ps：内置了几种假期安排的下载途径，可以根据需求，在“下载当年假期安排”节点自行更改。

暂时只写了框架功能，其他功能后续慢慢写。
