Log metrics regarding the addresses that are submitted and the resultant flooded images

[marpaia]

In production, it will be useful to understand the regions where people are interested in climate change as well as the efficacy of our models. For this reason, we need to log the requested address, the raw image we get from streetview, and the flooded image.

Let's also make sure that we have our legal and privacy ducks in a row before implementing this. A set of terms from a website like Montreal Data License might be useful for this.
