main: Deep sleep for up to an hour 

It really isn't necessary to have minute-level granularity of soil
moisture (especially since it's just been sitting at "max" for 2
weeks!).  Updating frequently is helpful for diagnostics, though.  To
compromise, the sensor will now publish data every minute for the first
few minutes after it starts up, then reduce its update frequency to once
every hour.
