代码说明： 1. 压缩体积设置： ◦ 在 compress_image 方法中，将图片压缩到最小体积，使用 thumbnail((400, 300)) 和 quality=10。 2. 工具栏： ◦ 在 _create_tool_bar 方法中，创建工具栏并添加打开图片、选择保存文件夹和压缩图片的按钮。 ◦ 绑定工具栏按钮的事件。 3. 清除图片： ◦ 添加了 clear_image 方法，用于清除当前显示的图片。 ◦ 在 on_compress_single 方法中，压缩完成后调用 clear_image 方法清除当前显示的图片。 4. 其他功能： ◦ 保留的功能，包括打开图片、选择保存文件夹、压缩图片和退出程序。

工具栏图标比较丑，可以自己更换
