Tor add-on to protect against guard discovery and related attacks

This add-on uses the Stem Tor control port library to connect to a Tor control port listening on port 9051 (or on an alternate user-specified port, or UNIX file system socket). This addon protects against guard discovery and related traffic analysis attacks. A guard discovery attack enables an adversary to determine the guard node(s) that are in use by a Tor client and/or Tor onion service. Once the guard node is known, traffic analysis attacks that can deanonymize an onion service (or onion service user) become easier.
