Range slider emits relayout evt on mousemove, should be only on mouseup

I have had the need to do something after the rangeslider had changed (update the min/max somewhere else on the page). I did not find any event that fired only after the slider had been released (a.k.a. mouseup) so I changed the rangeslider/draw.js:

function mouseUp() {
            dragCover.removeEventListener('mousemove', mouseMove);
            dragCover.removeEventListener('mouseup', mouseUp);
            Lib.removeElement(dragCover);
// --> new code
            gd.emit('plotly_rangesliderend', {
                axis: axisOpts,
                opts: opts
// --> end new code
            });

Is this anything that would be merged? Should I do a PR?

从 rangeslider/draw.js 中的 mouseUp 开始，并将其与发出 relayout 事件的 mousemove 路径进行比较。在决定所需行为是修改 relayout 事件还是新增 end 事件之前，追踪现有的 rangeslider 事件处理和覆盖情况。事件行为符合 issue 的 mouseup-only 要求即表示完成。
