bug: progress may reach 100%

[DrssXpro]

In mathematics this formula (1 - Math.exp(-1 * this._time / this.timeConstant)) may never reach 1, but in computer it does，like this：

if timeConstant set 100，You can see my progress bar component is reaching 100 very quickly：

So I think we can add a limit to the operation of setting the progress 🤔：

setProgress(Math.min(progress, 0.9999999999999999))

Of course we can set timeConstant to avoid reaching 1 as much as possible (This is what we currently do in our project 😄)
