fork 自https://bitbucket.org/amahta/qvncclient.git 我做了一些工作：
- 增加了WebSocket的支持，并且使用状态机优化握手链接，以适应qt for WebAssembly。
- 修复了在macos上渲染的颜色错误
代码在Qt6.5.2上测试通过，如果是Qt5.x的版本，可能需要非常简单修改一下代码，但应该也是没太大问题。

以下为原始的README.md
QVNCClient is a Qt Widget that can be used to view and control remote VNC supported hosts (servers)
QVNCClient does not include any OS dependent code and therefore it can be easily used on any platform supported by Qt.
Just drop a QWidget on your user interface and promote it to QVNCClientWidget, as simple as that.
