docs: Creates a CTRL file object from a dictionary. The dictionary
          must contain the items "ALAT", PLAT" and "SITE".
  
          Valid dictionary items are:
              ALAT: the a-lattice parameter
              PLAT: (3x3) array for the lattice vectors
              SITE: list of dictionaries: {'ATOM': class label,
                                           'POS': (3x1) array of fractional
                                                  coordinates}
              CLASS (optional): list of unique atom labels as str
              SPCGRP (optional): space group symbol (str) or number (int)
              HEADER (optional): HEADER text as a str
              VERS (optional): LMTO version as a str
  
          Args:
              d: The CTRL file as a dictionary.
  
          Returns:
              An LMTOCtrl object.
