58 PURPOSE : Decode PER OBJECT IDENTIFIER type

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