调用CMD命令的一个.NET工具类（MyWindowsCmd）

功能大概描述一下如果直接StandardOutput.ReadToEnd()这种方法，有很多限制

这类方式必须把命令全部执行一次写入并标记为exit，而且返回内容的获取会一直等待，如果在主线程里使用会导致假死。

若遇到执行时间长，同时会在执行中输出进度的命令，则明显不适应

对于部分特殊字符这类方法会直接中断一直等待（特别是对包含asc颜色等样式的输出）

本文的工具类解决以上问题，使用委托订阅的方式即时的输出执行过程，不用等待，异步输出结算后自动退出

方便应对类似这种需要长时间运行即时输出的打包命令。

下面直接贴出代码，方便后面的朋友 直接使用。

前一个类StreamAsynRead是用于读取cmd进程返回流IO 后面的MyWindowsCmd为cmd主要功能
