Heat index

This is another indicator developed by our former colleague Nadia. In this case, the code is not in the format of CSIndicators, but it could be converted: https://earth.bsc.es/gitlab/es/sunset/-/blob/working-branch-nadia/modules/Indicators/R/heat_index.R https://earth.bsc.es/gitlab/es/sunset/-/blob/working-branch-nadia/modules/Indicators/R/tmp/HeatIndex.R

Again, @rmarcos may know the details, so he may be willing to support with the description or documentation.

Please, let me know if you want to discuss these indicators.

Cheers,

Núria
