 * A function that retrieves offset and information for a specific primitive within a data schema.

 * ```ts
 * const Boid = d.struct({
 *  position: d.vec3f,
 *  velocity: d.vec3f,
 * });
 * const memLayout = d.memoryLayoutOf(Boid, (b) => b.velocity.y);
 * console.log(memLayout.offset); // Byte offset of velocity.y within Boid (here 20 bytes)
 * console.log(memLayout.contiguous); // Contiguous bytes available from that offset (here 8 bytes)
 * ```
 *
 * @param schema - The data schema to analyze.
 * @param accessor - Optional function that accesses a specific element within the schema. If omitted, uses the root offset (0).
 * @returns An object containing the offset and contiguous byte information.
