1.23 Integrated Heat Dispenser not fully cooling off

According to the wiki, the IHDs are supposed to freely exchange heat among the neighboring components, it's self, and the reactor hull so that the temperature is equal.

However, the temperature of all the IHDs remain very slightly above 0 long after my reactor has cooled off. Long after all the neighboring cooling cells have returned to normal. The IHDs should always balance the heat such that they wind up with the empty portion of any remainder.

Probably better would involve adding a mask of the low bit to the result of the existing check function (effectively always round up, but for integer and to the nearest even number).

EG:
Replace:
HeatDiference = Delta >> 1
With:
HeatDifference = Delta >> 1 + Delta & 0x1

Edit: I am presuming that calculating /if/ there is a difference occurs at a different stage than distributing the net delta.
