Ideal wet bulb temperature sensor

## Information

This sensor outputs the wet bulb temperature of the medium in the flow between its fluid ports. The sensor is ideal, i.e., it does not influence the fluid. If the parameter `tau` is non-zero, then its output is computed using a first order differential equation. Setting `tau=0` is not recommend. See BuildingSystems.Fluid.Sensors.UsersGuide for an explanation.

## Revisions

- October 24, 2022, by Michael Wetter:
  Improved conversion from `Xi` to `X` so that it also works with media that have `reducedX=true`.
  See #1650.
- February 21, 2020, by Michael Wetter:
  Changed icon to display its operating state.
  This is for #1294.
- January 18, 2016 by Filip Jorissen:
  Using parameter `tauInv` since this now exists in BuildingSystems.Fluid.Sensors.BaseClasses.PartialDynamicFlowSensor. This is for #372.
- September 10, 2013 by Michael Wetter:
  Set `start` attribute for `wetBulMod` to use consistent start values within this model.
- June 3, 2011 by Michael Wetter:
  Revised implementation to add dynamics in such a way that the time constant increases as the mass flow rate tends to zero. This significantly improves the numerics.
- February 18, 2010, by Michael Wetter:
  Revised model to use new block for computing the wet bulb temperature.
- September 10, 2008, by Michael Wetter:
  Renamed output port to have the same interfaces as the dry bulb temperature sensor.
- May 5, 2008, by Michael Wetter:
  First implementation. Implementation is based on BuildingSystems.Fluid.Sensors.Temperature.
