Create more performant voxel rendering example

Current voxel rendering example is based on the classic Raytracing technique and doesn't work well for not very small grid dimensions. We should create a new example, based on the previous one, that doesn't check intersection with very voxel, but rather, for example, follows the ray from origin, finding first intersection and moving on to the closest intersecting neighbor and continuing on this operation until the intersecting voxel is active.

Start by locating the existing voxel rendering example referenced in the issue and compare its ray-intersection loop with the proposed traversal. Create a separate example that follows the ray through neighboring voxels instead of checking every voxel, and verify that it renders active voxels efficiently on larger grid dimensions.
