+ 修复了python>=3.9时的module 'collections' has no attribute 'Iterable’报错
+ 修复了当出现报错导致上传不成功时仍更新文章md5的json存储文件的bug(此bug会导致当报错文章未上传成功时且未更新时，不能二次上传的问题)
+ 将配置项和代码分离,只需运行myblog.py后填写对应配置即可
+ 增加poetry支持,构建更加简便快捷
+ 优化代码结构，更新README.zh-CN.md说明文件
+ 更改.replace为.strip，现在只会过滤后缀的.md，不会替换文件名中的.md
+ 增加了一个CHANGELOG.MD文件，可以看到版本的功能更新
（过多的差异是因为black自动格式化了代码，实际上修改并没有那么多）
