Run-Length Encoding (or RLE for short) is a type of compression that encodes sequences of repeating values in just a few bytes!
In our case, we want to use RLE to compress voxel volumes, so we first have to make our volume sequential. This is usually done by chunking our volume and storing our voxels in a one-dimensional array, with some spatial indexing scheme on top. Once that is done, we can get started!
One rather simple way to do RLE is to write a number indicating repetitions, followed by the thing to repeat...
