  PURPOSE : Decode PER OBJECT IDENTIFIER type 

            The PER encoding of an open type is preceded by a length 
            determinant (1 or 2 bytes as long as no data fragmentation is
            necessary). The bit field of the encoded open type itself is  
            octet aligned octet string.
            If the result of encoding the outermost value is an empty bit 
            string, the bit string must be replaced with a single octet 
            with all bits set to 0.
