Description

We can specify the direction with a symbol (:C, :R) and specify the row / column color as input.
It will be less efficient than decompress! but the goal of this method is to reduce memory requirements for very large problems.
With an efficient vectorized decompression (great for GPU), it is the other advantage of star coloring / bicoloring over the acyclic coloring / bicoloring.

Research direction

Start by locating the existing decompress! implementation and the star bicoloring code. Determine the intended :C and :R inputs, row or column color handling, memory requirements, and expected vectorized behavior; done should include a working decompress_single_color! method for both directions with coverage for its results.
