Fixes to HeatRejection

[JasonGlazer]

To clarify if the fan power is electric input or motor nameplate power, change "fan_power" to "fan_electric_input_power" and add a new data element called "fan_nameplate_power"

For Appendix G, the baseline system is supposed to use a condenser water setpoint from table G3.1.3.11, which varies by climate zone. This is usually not the same as the cooling tower design leaving water temperature, which we would derive from the design wetbulb temperature and the approach. To fix this, add a new data element called "leaving_water_temperature_setpoint"

Per Neal's suggestion make it "leaving_water_setpoint_temperature" instead with dimension as the last part of the name.

Addressed this and also fixed other places where temperature did not end data element name as part of update to 0.0.20
