网络测试工具
工具介绍：
这是一个功能完整的网络测速工具，可以测试网络的下载速度、上传速度和延迟。
功能特点：
1. 速度测试
- 下载速度测试
- 上传速度测试
- Ping延迟测试
- 自动选择最佳服务器
2. 实时显示
- 进度条显示测试进度
- 实时显示测试状态
- 清晰的数据展示
3. 历史记录
- 保存测试历史
- 显示最近6次测试结果
- 支持导出历史记录
使用要求：
- Python 3.6+
- 需要安装的库：
python -m pip install speedtest-cli
使用方法：
1. 安装依赖：
- 首先安装必要的库
- 确保网络连接正常
2. 开始测速：
- 点击"开始测速"按钮
- 等待测试完成（约1-2分钟）
- 查看测试结果
3. 历史记录：
- 自动保存每次测试结果
- 查看最近的测试历史
- 可导出完整历史记录
