forms实现快读阅读器

主要功能包括：
​​1.文本自动分块显示​​：按设定的速度逐词显示文本内容。
​​2.阅读控制​​：开始/停止按钮以及回车键控制。
​​3.界面自定义​​：包括字体、颜色（前景色和背景色）的设置。
​​4.暗黑模式​​：支持暗黑主题，并有相应的渲染器。
​​5.全屏模式​​：通过F11或按钮切换全屏。
​​6.速度调节​​：通过WPM（每分钟字数）数值调节器控制显示速度。
​​7.循环阅读​​：复选框控制是否循环阅读。
​​8.设置持久化​​：保存用户的设置（如字体、颜色、速度等）到配置文件。
​​9.文件自动加载​​：从固定路径加载文本文件。
​​10.错误处理​​：文件不存在或内容为空时的提示。
说明：
C:\Users\wangrusheng\AppData\Roaming\WinFormsApp38\settings.json
这个目录下，有一个json配置文件 主要配置字体，字体颜色，背景颜色，阅读速度等，第一次运行会自动生成
