using deprecated socks library

[zfil]

Hello

Please upgrade socks-proxy-agent to avoid using a deprecated socks library:

npm WARN deprecated socks@1.1.10: If using 2.x branch, please upgrade to at least 2.1.6 to avoid a serious bug with socket data flow and an import issue introduced in 2.1.0
npm notice created a lockfile as package-lock.json. You should commit this file.

socks-proxy-agent 4.0.1 has socks upgraded to 2.2.0.

Thanks
