refactor(models): respect model names/relpaths (#199)

Don't substitute path separators and "-" out of the model keys. Use the umodified relpath (respective to the root search dir) and just enforce "/" as separator.

This lets consumers set up example scenario workspaces with model subdirs like root / key, such that example scenarios with multiple models, some of which expect to find outputs of previously run models by relative path, will just work.
