Addressing a Problem?

Add indicator allowing the computation of wind power potential.

Potential Solution

Here is one ref which fits wind speed to a Weibull distribution, then integrates over all wind speeds to get the potential assuming power is proportionnal to V cubed.

In practice, there are cutoff speeds (25 m/s) after which power production drops to 0. See https://www.nrel.gov/docs/fy14osti/61714.pdf

Additional context

Wind speed has often a diurnal component, so not clear how accurate computations based on daily values would be. Probably best to mandate hourly wind speeds here, but recommendations from knowledgeable folks would be useful.

### What kind of change does this PR introduce?

* Adds two indices and their indicators: wind_profile and
wind_power_potential.

### Does this PR introduce a breaking change?
No


### Other information:
Ideally we`d add an indicator to compute air density, which is an
optional input to the wind power potential.
