New indices from thermodynamic variables: Dew point, Wet bulb temperature, etc

[SarahG-579462]

Addressing a Problem?

The social medias are talking lots about wet bulb temperature as a metric for survivability. Might be interesting to add it, and other thermodynamic variables, such as dew point, to xclim.

Potential Solution

Indicators for:

• Wet bulb temperature
• Dew point
• Others?

Conversions like this are already implemented in MetPy which is well maintained. I don't think re-coding them is worth it. However, once upon a time, I did a proof-of-concept (#726) to see if we could make indicators from MetPy's function. Turn's out that it did work, but with some issues. I know they have done a lot of work since, especially to better integrate with xarray and dask. The wrapping idea could be revisited!

Cool - thanks for pointing me towards that package.

I'd add air density to the wish list. It comes up in wind power computations.
