The extension-added signal is emitted when a new extension has been
added to the #PeasExtensionSet. It happens when a new plugin implementing
the extension set's extension type is loaded.
You should connect to this signal in order to set up the extensions when
they are loaded. Note that this signal is not fired for extensions coming
from plugins that were already loaded when the #PeasExtensionSet instance
was created. You should set those up by yourself.
