Index file importing multiple files messes up results

I'm using sequelize and I have a `models/index.js` which does this:

```
import { Car } from './car.js'
import { Bike } from './bike.js'

// ... defining sequelize relations here ..

// then:

module.exports = {
Car, Bike
}
```

Then if another file `vehicularMadness.js` imports Car via this index file, also bike.js gets calculated as imported by `vehicularMadness.js`. And in fact all files that `module/index.js` imports get assigned the same usage.

Is there a way to configure deprank to not work like this or is there another tool that does not do this?
