SGP/SWATS/E5 - Incorrect soil moisture data

The temperature rise values were too high (> 20 deg C).  Water potential is calculated 
from a rise (and subsequent drop) in temperature in the sensor that is normally ~1-5 degrees 
C.  When the T_rise is too high, the soil moisture data is dubious at best and unusable 
at worst.

Soil temperatures are OK.
