Hello!

As example without writer

package main

import (
	"github.com/gosuri/uilive"
)

func main() {
	writer := uilive.New()

	// start listening for updates and render
	//writer.Start()

	writer.Stop() // flush and stop rendering
}

we go to panic on Stop().
How I see befor 57b6e55 we not go to panic without Start().
Was it done on purpose?
Or it can be ignored in library like mrqwer88@7da1a80 as example?

Thanks in advance!
