+ It is similar to get highest bit, it would turn an 001010 into an 001111 so basically the highest bit and all below.
+ We then invert this, so we'd have 110000 and compare that to the "main" chunk.
+ This is because the bug only appears when the current chunks lightmaps are higher than those of the neighbors, thus we can omit sending neighbors which are lower than the current chunks lights.
+
+ so TLDR is that getCeilingLightMask returns a light mask with all bits set below the highest affected section. We could also count the number of leading zeros and invert them, somehow.
