Feature request: reverse arrow style

Thanks for this library @pierpo , it’s very nice.

The way element relations work, all relations to a source element must be known at the time the source element is rendered. Sometimes it would be programmatically convenient to express all relations to a target element instead of a source element. We could accomplish this by adding a single flag to the arrow style that indicates that instead of being drawn forward, with the arrowhead pointing at the target, the arrow should be draw backward, with the arrowhead pointing at the source.

Style
{
  strokeColor: string,
  strokeWidth: number,
  strokeDasharray: number,
  arrowLength: number,
  arrowThickness: number,
  noCurves: boolean,
  arrowForward?: boolean    // New property. Defaults to True.
}

Then in generateAllArrowMarkers draw the arrowhead pointing at the source if the arrowForward property is False.

Should be solved by https://github.com/pierpo/react-archer/pull/139 😉

It makes sense indeed. I’ll have a look when I find some time! Thank you for the suggestion 🤗
