把可执行文件下载后，移动到你想转换的目录，双击运行，则该目录及子目录下的webp都会被转换为jpeg。
质量基本不会有损失（肉眼看着无损，不是真的说无损哈，别怼我了😭）
使用协程并发执行，提高性能
After downloading the executable file, move it to the directory you want to convert, double-click to run, and the webp in the directory and subdirectories will be converted to jpeg. There is basically no loss of quality
Use coroutines for concurrent execution to improve performance
