docstr: Provide ourselves as a module loader.
  
  Parameters
  ----------
  fullname
      Name of module to be imported, if it starts with the name
      that we are using to wrap, we will deliver ourselves as a
      loader, otherwise defer to the standard Python loaders.
  
  Returns
  -------
  A ModuleSpec with ourself as loader if we're interposing,
  otherwise None to pass off to the next loader.
