docs: Return analysis of library dependencies with a Python wheel
  
      Use this routine for a dump of the dependency tree.
  
      Parameters
      ----------
      wheel_fname : str
          Filename of wheel
      filt_func : None or callable, optional
          If None, inspect all files for library dependencies. If callable,
          accepts filename as argument, returns True if we should inspect the
          file, False otherwise.
  
      Returns
      -------
      lib_dict : dict
          dictionary with (key, value) pairs of (``libpath``,
          ``dependings_dict``).  ``libpath`` is library being depended on,
          relative to wheel root path if within wheel tree.  ``dependings_dict``
          is (key, value) of (``depending_lib_path``, ``install_name``).  Again,
          ``depending_lib_path`` is library relative to wheel root path, if
          within wheel tree.
