Setting buildPath and runtimeLoadPath from script

[pdinklag]

ExternalCatalogSetup has had its buildPath and runtimeLoadPath values be changed in type. This will result in empty values on your external catalog objects upon upgrading, and content builds failing. The types have been updated to work with Addressables' ProfileValueReference framework. This allows to work with the built-in string evaluation functions and profile-defined variables in a more transparent way as it also properly previews the result in the inspector window.

Could you give a small description as to how I'd set these from a script now?

I used to do this:

var catalog = CreateInstance<ExternalCatalogSetup>();
catalog.CatalogName = bundle.name;

catalog.BuildPath = BundlesBuildPath + "/" + bundle.name;
catalog.RuntimeLoadPath = RuntimeLoadPath;
catalog.AssetGroups = groupList;
catalogs.Add(catalog);

If I have an external catalog asset, I can select <custom> in the inspector and set some value. How would I do that from script? Creating a dummy external catalog asset and borrowing the profile value references from there also does not seem to do the trick. (this does work, but apparently I'm running into #21 )
