SGP/EBBR/E20 - Reprocess: Soil Heat Flow #4 Incorrect

Soil heat flow #4 was incorrect because it's wires were loose from the connection 
terminals.

Average soil heat flow, sensible heat flux, and latent heat flux were affected; these can 
be recalculated using the remaining good sets of soil sensors as follows:
   ave_shf = (g1 + g2 + g3 + g5)/4
   e = -(q + ave_shf)/(1 + bowen)
   h = -(q + e + ave_shf)
