Basic Iced applet, but it should be noted that the time update
logic is a significant improvement. The milliseconds until the
next whole minute is calculated, then via tokio the thread sleeps
until then. Meaning that the clock applet is only running
(from my testing) for 3 milliseconds a minute. This takes less
recources and is more accurate than checking every second from
app start like the old gtk applet did.
