Could you support set/getThumbDrawable about seekarc HOT 1 OPEN

Hi, I want to do the same thing - Changing the thumb during runtime.
So I looked at their code and find a way to do that.
The idea is simple, just copy their SeekArc as a base one and made modifications on it to get extra functions, then use the local new class as a replacement.
I do not know how to modify the library managed by gradle. So this is an alternative way from the stackoverflow.

Step 1, download the SeekArc.java from this repo and put it somewhere in your project. Now you have a local SeekArc class yourself and you can modify it then use it as custom view.
Step 2, insert the following code

    public void setmThumb(Drawable newThumb){
        mThumb = newThumb;
        int thumbHalfheight = (int) mThumb.getIntrinsicHeight() / 2;
        int thumbHalfWidth = (int) mThumb.getIntrinsicWidth() / 2;
        mThumb.setBounds(-thumbHalfWidth, -thumbHalfheight, thumbHalfWidth,
                thumbHalfheight);

        invalidate();
    }

And that is it.
You just need to replace the official SeekArc with your custom one and you could get/set the thumb.
I did not write the get method, but it is obvious as you can see from the set method.
PS : I did not test this method with different sizes of thumb, but it seems should work fine.
