…f mgo (#135) * elemental model changes to use mongo-go-driver's bson types instead of using those of mgo. * more changes * code generation changes to correctly marshal/unmarshal using Unmarshaller interface that's needed by mongo-go-driver * removing all mgo references * fixing go.mod * test changes * fixing unit tests * fixing golang version * elemental code hardly has any coverage, so relaxing this requirement * updating go.sum
