What's Changed
* Variables as toppings by signedav in https://github.com/opengisch/toppingmaker/pull/14
When we pass path_variables to the ExportSettings we resolve those. Means we take the variable as file path, get the file, create a topping file from it and write into the variable a resolved path (in Model Baker Topping Exporter this will result in an ilidata key).
