[Feature]可以使用python代码调用的方式，而不是命令行的方式吗

**思路和建议**

有时需要批量下载，想用python代码指定下载内容，能否支持用python调用的接口。

**参考代码**
提供代码参考

Look at the existing command-line interface in the codebase to understand how download commands are structured. Identify the core functions that handle searching and downloading music. The goal is to expose these functions as a Python API that can be called programmatically, allowing batch downloads. Check if there are any existing modules or classes that can be refactored into a library.
