/**
 * Build a binary radix tree over the given leaves and Morton codes.
 *
 * @param {BVH} bvh
 * @param {number[]|Uint32Array} leaf_nodes
 *        Pre-allocated leaf node IDs, ordered to match `sorted_morton_codes`
 *        (i.e. leaf_nodes[i]'s code is sorted_morton_codes[i]).
 * @param {number[]|Uint32Array} sorted_morton_codes
 *        Morton codes in non-decreasing order. May contain duplicates.
 * @param {number} leaf_count
 *        Number of leaves (must equal the length of `leaf_nodes` and
 *        `sorted_morton_codes` that the function will actually look at).
 * @param {number[]|Uint32Array} internal_nodes
 *        Pre-allocated internal node IDs, of length at least `leaf_count - 1`.
 *        Ignored when leaf_count < 2.
 * @returns {number} The root node id, or NULL_NODE if leaf_count is 0.
