Add option to block TOR exit relays

Nobody has claimed this yet.

Some customers may wish to block tracking requests from TOR exit nodes, since these can often be used for more nefarious reasons than just normal browsing.

It is important to note that there may exist relays that do not allow TOR exits from that relay, but are only used to pass traffic within the TOR network, we would preferably only want to have the option to block exit node IPs from being tracked.

There exists this GitHub repo which has a list of IPs: https://github.com/SecOps-Institute/Tor-IP-Addresses
As well as this website https://www.dan.me.uk/tornodes
Which provides an exit node IP list: https://www.dan.me.uk/torlist/?exit

There may be other methods of gathering TOR exit node IPs.

Start by reviewing the plugin's tracking-request handling and the referenced Tor exit-node IP sources. Define how the option obtains and refreshes exit-node addresses while excluding non-exit relays; done means customers can enable blocking of Tor exit-node tracking requests without blocking other Tor traffic.
