Subject: [PATCH] iamb: use correct config directory on macOS

On macOS, configuration files are stored in the platform-standard
directory `~/Library/Application Support/` by default. However, if the
user enables the XDG Base Directory specification by setting
`xdg.enable = true`, iamb should respect the `XDG_CONFIG_HOME`
environment variable (along with other related XDG variables).
Currently, this behavior is not implemented in iamb, a PR has been
opened to fix that -> https://github.com/ulyssa/iamb/pull/478.
