Root direction for forests not working

[TheKohnka]

Description

Setting the root directions of a forest causes both the root locations and root directions to not be respected. Not setting the root direction causes the location to be respected, so I think the root direction is causing some issue. This happens both in convex and nonconvex domains.

Reproduction

    root1 = np.asarray(ROOT_LOCATION, dtype=float).reshape(3,) * L
    root2 = -root1
    use_dir = args.use_root_dir.lower() == "true"
    if use_dir and ROOT_DIR is not None:
        dir1 = np.asarray(ROOT_DIR, dtype=float).reshape(3,)
        dir2 = -dir1
    else:
        dir1 = None
        dir2 = None

    forest = Forest(n_networks=1, n_trees_per_network=[2], physical_clearance=float(args.forest_clearance))
    forest.set_domain(domain)
    forest.set_roots(start_points=[[root1, root2]], directions=[[dir1, dir2]])

Expected behavior

Expect roots to be at root locations pointing in root directions. However, when root directions are specified, neither the location nor the direction are proper.
