Is there a helper to generate a sequence of port numbers to try?

Yes, there is. The `portNumbers()` helper generates a sequence of port numbers in a given range [index.js:L169-L194].

You can use it like this:

```js
import getPort, {portNumbers} from 'get-port';

console.log(await getPort({port: portNumbers(3000, 3100)}));
// Will use any port from 3000 to 3100, otherwise fall back to a random port
```

The function takes two parameters:
- **`from`**: The first port of the range (must be between 1024 and 65535)
- **`to`**: The last port of the range (must be between 1024 and 65535 and greater than `from`)

The `portNumbers()` function returns an iterable that generates port numbers sequentially from `from` to `to` [index.js:L183-L188], which can then be passed to the `port` option of `getPort()` [index.d.ts:L3-L9].
