Added a new output "Aggregated Exposure Values"

[micheles]

For the WFP project.

Should we call the new output and the corresponding filename agg_exposure? agg_keys is not very intuitive for the user.

I was thinking about agg_tags and aggrisk_tags since the aggregation is by tags, but I am open to suggestions. The final user will not see the name much in any case.

Is this aggregated risk or aggregated exposure though?

The final user will not see the name much in any case.

It does show up in the output filename, eg. agg_keys_5.csv

There is also a hidden output aggrisk_keys which is meant to be used programmatically (for instance in the risk profiles):
