implemented daemon
naxalnet is now a daemon! When run from systemd, it checks for new
devices or removal of devices and reloads the wifi configuration.
Updated the systemd service and changed Type to notify. Unfortunately,
there is some problem with logging. The messages from naxalnet.iwd could
not be found in the systemd journal or while running without --systemd.
