Usage phase WCF (Water Consumption Footprint)

[adrienbanse]

This PR includes the computation of the WCF "Water Consumption Footprint" of the usage phase of the request. The methodology is based on https://arxiv.org/abs/2304.03271.

It remains to

• Write the corresponding documentation

To discuss (@samuelrince) :

• Maybe we should write a personnalised logger message if the user tries to access request.impacts.embodied.wcf
• For now response.impacts.wcf = response.impacts.usage.wcf, which may be misleading. How should we handle this?

Closes #85.

Hello, nice work there!

I was just wondering : where did you get the data on electricity WUE by country from?

By the way, this might interest you, AWS has published the PUE and WUE for each data center region. It's available for download as a CSV file here -> https://sustainability.aboutamazon.com/products-services/aws-cloud

at "See available regions PUE and WUE"
