Add PGPPacket._symmetric_key_algorithms

From RFC 4880 [1]:

       ID           Algorithm
       --           ---------
       0          - Plaintext or unencrypted data
       1          - IDEA [IDEA]
       2          - TripleDES (DES-EDE, [SCHNEIER] [HAC] -
                    168 bit key derived from 192)
       3          - CAST5 (128 bit key, as per [RFC2144])
       4          - Blowfish (128 bit key, 16 rounds) [BLOWFISH]
       5          - Reserved
       6          - Reserved
       7          - AES with 128-bit key [AES]
       8          - AES with 192-bit key
       9          - AES with 256-bit key
       10         - Twofish with 256-bit key [TWOFISH]
       100 to 110 - Private/Experimental algorithm
