Pull timestamp from log instead of creating timestamp on parse

[tuckshoprn]

If the script gets restarted at any point, it reparses the entire log and creates new entries with current timestamps for all the logged ips. Is it possible just to pull the timestamp from the log instead of creating a timestamp?, that way duplicates can be removed, or at least wont show up as new connections?

I have also added a pull request to makarai/nginx-proxy-manager-graf to change the sendips script to reflect the different naming convention that nginx proxy manager seems to be using for its log files now.

This is a great project, thank you for your time.
