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

Question

Yes, there is. The `portNumbers()` helper function generates a sequence of port numbers in a given range [index.d.ts:L83].

According to the documentation, `portNumbers(from, to)` returns an `Iterable` for port numbers in the given range. The `from` parameter must be in the range `1024`...`65535`, and `to` must also be in that range and greater than `from` [index.d.ts:L66-L82].

Here's how you use it [readme.md:L37-L40]:

```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
```

This is useful when you want to check a specific range of ports before falling back to a random available port.
