shadowsocks-rust 1.20.0 on Rust Cargo

Breaking Changes

#887 shadowsocks stream cipher (TABLE) doesn't need to make a derived key instead of using user's predefined key directly. This change will make shadowsocks-rust not going to be compatible with its older version. Users who are using TABLE cipher should upgrade all your local and server instances to the latest version of shadowsocks-rust. On the other hand, TABLE cipher is marked deprecated because it is vulnerable, users must migrate to other more secured methods immediately.
