Track which direction the current node's light came from, and don't check it again when we check the current node's adjacent blocks. e.g. if this node was the eastern neighbour of a light source, we don't need to check this node's western neighbour, as we already know it has a higher light level than our own. This improves performance of basic light spread in a void by about 6%, which isn't a huge amount, but it's something. I've yet to explore whether light removal could also benefit from this change.
