Hello,

First of all, thank you for this package.

Current implementation use home dir and hardcoded .config. Are there any chance to follow XDG Base Directory Spec? With this way, users can easily backup their configuration and program states.

Program should check $XDG_CONFIG_HOME environment variable for store buds settings. ~/.config/livebuds/config.toml -> $XDG_CONFIG_HOME/livebuds/config.toml (if environment variable exists).
