fix: use with shadowsocks transport

[greenhat616]

As #151 (comment) illustrated,

• should do a alias plugin-opts for plugin_opts to compatible with clash and clash-meta
• revert simple-obfs plugin and just print a warning deprecated until v2ray-plugin get implemented and widely used.
  • impl tls simple-obfs, like https://github.com/MetaCubeX/Clash.Meta/blob/Alpha/transport/simple-obfs/tls.go
