Importing SQL raw-loader module not found

I have a simple issue when running `func` or `npm run start`.

in package.json I have
```
....
start: "func",
...
```

on my project file I have
```
...
import sqlInsert from 'foo.sql'; // this is a simple sql file
,,,
```

```
//foo.sql
SELECT * from Table;
```

When I `npm run start` it shows the following error.
`Exception: Worker was unable to load function GetDataProviderResponse: 'Error: Cannot find module 'foo.sql'`

Start with the package.json start script and the function entry point that imports foo.sql. Reproduce the failure with npm run start and func, then trace the module-loading error to determine how this project handles .sql imports. Done means the documented or implemented behavior is clear and the function loads successfully in the reported setup.
