docs: Check if a module comes from the given experiment path.
  
      Check if a module, given by name and filename, is from (a subdirectory of )
      the given experiment path.
      This is used to determine if the module is a local source file, or rather
      a package dependency.
  
      Parameters
      ----------
      filename: str
          The absolute filename of the module in question.
          (Usually module.__file__)
      modname: str
          The full name of the module including parent namespaces.
      experiment_path: str
          The base path of the experiment.
  
      Returns
      -------
      bool:
          True if the module was imported locally from (a subdir of) the
          experiment_path, and False otherwise.
