/**
 * Get a smooth step path from source to target handle
 * @param params.sourceX - The x position of the source handle
 * @param params.sourceY - The y position of the source handle
 * @param params.sourcePosition - The position of the source handle (default: Position.Bottom)
 * @param params.targetX - The x position of the target handle
 * @param params.targetY - The y position of the target handle
 * @param params.targetPosition - The position of the target handle (default: Position.Top)
 * @returns A path string you can use in an SVG, the labelX and labelY position (center of path) and offsetX, offsetY between source handle and label
 * @example
 *  const source = { x: 0, y: 20 };
    const target = { x: 150, y: 100 };
