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 within a specified range.

The function is exported from [index.js:L169-L194] and accepts 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 or equal to `from`)

It returns an iterable (a generator) that yields all port numbers in the range from `from` to `to` (inclusive).

**Example usage** [readme.md:L98-L101]:
```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 validates its inputs and throws errors if parameters are not integers [index.js:L170-L171], out of the valid port range [index.js:L173-L179], or if `from` is greater than `to` [index.js:L181-L183].
