请支持通过环境变量制定数据缓存目录

大神你好，我使用efinance库在streamlit cloud上部署一个简单的应用，会报如下错误。原因是efinance库会建立缓存目录，而在云端环境有权限限制。能否在相应位置增加通过环境变量制定数据缓存目录的功能，谢谢

PermissionError: [Errno 13] Permission denied:

'/home/adminuser/venv/lib/python3.9/site-packages/efinance/config/../data'

Start by tracing the cache creation from the reported efinance/config/../data path and identify where the data directory is selected. Add support for choosing that directory through an environment variable, then verify that a writable location can be used in the Streamlit Cloud deployment without the reported PermissionError.
