Write systemd service files

For example, it would be useful for a server to track a list of ASNs that it wants to block and allow, run the asn-to-ipset-script.sh automatically on the list every day or week, and apply the output scripts locally if they have changed.

It would be useful to run ua-s-a-d.sh as a service.

Related to TechnologyClassroom/WebServerWatcher#2 , here is a temporary command to run WebServerWatcher and ua-s-a-d.sh:

tmux a || tmux new-session -d 'cd ~/firewallblockgen/ && while true; do bash ua-s-a-d.sh ; sleep 600 ; date; done' \; split-window -v 'cd ~/webserverwatcher/ && python3 webserverwatcher.py' \; split-window -v 'cd ~/webserverwatcher9/ && python3 webserverwatcher.py' \; attach
