Touch support stopped working

[jesben]

Thanks for a great lib to all those who contributed!

When this library switched to mousedown, mousemove and mouseup from drag "onmove, onstart and onstop" for bar events, touch support stopped working (Tested on iOS). Tried to implement it with touchstart, touchmove and touchend, but scrollbar from container messes it up and dragging bar doesn't run smoothly. Anyone have a solution for this?

Both mouse and touch works in the demo! The demo runs with a very old version. Version 0.0.7 is the last version that uses onmove, onstart and onstop.

To get offsetX and offsetY, I have tried with
touchstart:

const rect = e.target.getBoundingClientRect();
x_on_start = e.targetTouches[0].clientX - rect.x;
y_on_start = e.targetTouches[0].clientY - rect.y;

touchend:

const rect = e.target.getBoundingClientRect();
let offsetX = e.targetTouches[0].clientX - rect.x;
let offsetY = e.targetTouches[0].clientY - rect.y;

[jesben]

x_on_start = e.touches[0].clientX;
y_on_start = e.touches[0].clientY;

let offsetX = e.touches[0].clientX;
let offsetY = e.touches[0].clientY;

Is working :)

I'm sorry - I do not quite understand the fix @jesben. Could you push a PR, please?
