Package-level declarations

If you're using Kotest, add this to your AbstractProjectConfig. See here for high-level docs.

If you create a class named SelfieSettings in the package selfie, it must extend this class, and you can override the methods below to customize various behaviors of selfie. You can also put the settings class somewhere else if you set the selfie.settings system property to the fully qualified name of the class you want selfie to use.

This is automatically registered at runtime thanks to META-INF/services.
