配置文件位置遵循XDG规范

[wi24rd]

man file-hierarchy

  ~/.config/
       Application configuration and state. When a new user is created, this directory will
       be empty or not exist at all. Applications should fall back to defaults should their
       configuration or state in this directory be missing. If an application finds
       $XDG_CONFIG_HOME set, it should use the directory specified in it instead of this
       directory.

建议用 .config/ydcv/ydcv.conf 或者 .config/ydcv.conf

I advice to use https://pypi.org/project/appdirs/.

appdirs has stopped maintenance. Use platformdirs to replace it.

I try to realize one alternative which use platformdirs to provide XDG function.
