add more encryption algorithms

[zero-github]

my ssh server only support the below encryption algorithms, but the library do not support,
could you please add these implementation or give me an example for one of them.
["aes128-cbc", "3des-cbc", "aes192-cbc", "aes256-cbc"]

[HsuJv]

Will do this ASAP.
BRs.

Hi there,

Pr #73 has already implemented the four algorithms. Please switch to v0.4 to enable 'em,

Note that there are some breaking APIs as the version number is grown up.
