0.3.0

1、支持自定义指示器图标（CapsGlow.exe目录下放capslock.png，如需支持主题可放capslock_dark.png + capslock_light.png）
2、自动保存配置
3、修复了目录存在自定义图标时未更新结构体中窗口大小字段的问题

1. Support custom indicator icons (capslock.png is placed in the CapsGlow.exe directory. If you need to support the theme, you can place capslock_dark.png + capslock_light.png)
2. Automatically save configuration
3. Fixed the issue that the window size field in the structure was not updated when the directory exists in a custom icon.
