Python 3.12 installation fails

```
× python setup.py egg_info did not run successfully.
│ exit code: 1

from imp import load_source
ModuleNotFoundError: No module named 'imp'
[end of output]
```

`imp` is deprecated and was removed with 3.12

首先找到仓库的 setup.py 以及 traceback 中显示的 imp 导入。验证在 Python 3.12 下的安装；当 package 可以在没有 ModuleNotFoundError 的情况下安装时，即表示完成。
