Compression is not yet supported

Hi,
I tried to extract a file from a rar and this is the error i get on my console "Compression is not yet supported". Does this mean that non-compressed file can't be extracted at this moment? If yes, when can we expect this library to support extracting compressed files?

Thanks

这个 issue 是关于为一个纯 JavaScript RAR reader 添加压缩支持。首先检查库的核心提取逻辑，可能位于主 rar.js 文件或解压模块中。查找现有的未压缩归档处理，并确定需要实现压缩算法的位置。检查是否有提取测试，以了解预期行为。'Done' 表示该库能够成功提取压缩的 RAR 文件，正如用户所报告的那样。
