Extend orderly_use_resource to orderly_use_depends

[athowes]

This could be helpful to allow writing longer, repetitive .yml dependencies using programming.

For example I might have a vector of country ISO3 codes that could be looped over to create .yml files like this one. It could have arguments for report, id, artefact (the name it has in the dependency) import_as (the name that it will have in the report).

(I think this is low priority and there are ways that you could do this using external ways of writing lines.)
