<p>Uses the suncalc module to generate an output at sunrise and sunset based on a specified location.</p>
<p>Several choices of definition of sunrise and sunset are available, see the <i><a href = "https://github.com/mourner/suncalc" target="_new">suncalc</a></i> module for details.</p>
<p>The first output emits a <b>msg.payload</b> of <i>1</i> or <i>0</i> every minute depending if between selected times or not.
The second output emits only on the transition between night to day (<i>1</i>) or day to night (<i>0</i>), and also once at the (re)start of the flow.</p>
<p>Also sets <b>msg.topic</b> to <i>sun</i> and <b>msg.moon</b> to the fraction of the moon between 0 and 1.</p>
