[BUG] String keys handed off to IMs code that expects ints

[skylerreid]

The InfrastructureModels function _populate_ref_it! operates on dictionaries that have string keys that can be parsed to integers. At some point, data is handed off to this function that has the string keys source, primary, and regleg. This causes the parse call in IMs to fail when it tries to convert these strings to integers.

See failing tests in ref_ravens_schema.

fixed in current version of ref ravens schema. the problem was a too-strict type check that was causing eng data to not be converted to math format before data was handed off to instantiate_model.
