Move socks5 env variables to CLI flags

[KingAkeem]

Currently the socks5 configuration variables are set within the .env file.

This is a pain to manage and can get confused if you run the command in a different directory.
To resolve this issue, add flags to set the host and port for SOCKS5 using the current values as the default.
