run himawaripy as a user service

Existing users should first stop, disable, and remove the old system timer and service:

    $ sudo systemctl stop himawaripy@$USER.timer
    $ sudo systemctl disable himawaripy@$USER.timer
    $ sudo rm /etc/systemd/system/himawaripy@.*

If the system timer is present in the trusted unit file, remove it.
