Reproduction of Expo tree shaking not removing unused code when using namespace imports

1. To reproduce the issue, first run an npm install.
2. Then, bundle the application for web by running npx expo export --platform web.
3. Notice that the final bundle (inside dist/_expo/static/js/web) includes both the function foo and the function bar, even though only foo is used inside index.ts.
4. Change the import in index.ts to a named import (import { foo } from './utils') and re-run npx expo export --platform web.
5. Notice that now the final bundle includes only the function foo, which clearly indicates that namespace imports are not tree-shaken in the same way as named imports.
