Cannot import internal common package.

[davidnewhall]

Now that host.Warnings has been moved into an internal package, how are we supposed to unwrap it?

I used to do this, but my code quit working when I updated this library to the latest release today. ie. go get ./... in my project.

	var warns *host.Warnings
	if !errors.As(err, &warns) {
		return fmt.Errorf("unable to get sensor temperatures: %w", err)
	}

	for i, w := range warns.List {
		fmt.Sprint("warning %v: %v", i+1, w)
	}

oh, unwrap... Yes, you are true. Then, I will make a PR about moving back Warnings to disk and host from common. Thank you so much!
