forms實現快讀閱讀器

主要功能包括：
??1.文本自動分塊顯示??：按設定的速度逐詞顯示文本內容。
??2.閱讀控制??：開始/停止按鈕以及回車鍵控制。
??3.界面自定義??：包括字體、顏色（前景色和背景色）的設置。
??4.暗黑模式??：支持暗黑主題，并有相應的渲染器。
??5.全屏模式??：通過F11或按鈕切換全屏。
??6.速度調節??：通過WPM（每分鐘字數）數值調節器控制顯示速度。
??7.循環閱讀??：復選框控制是否循環閱讀。
??8.設置持久化??：保存用戶的設置（如字體、顏色、速度等）到配置文件。
??9.文件自動加載??：從固定路徑加載文本文件。
??10.錯誤處理??：文件不存在或內容為空時的提示。

C:\Users\wangrusheng\AppData\Roaming\WinFormsApp38\settings.json
這個目錄下，有一個json配置文件主要配置字體，字體顏色，背景顏色，閱讀速度等，第一次運行會自動生成
