LZW/RLE handling #13
Description
The LZW/RLE handling currently set up is not idiomatic C# which also makes it hard to work with/reason about. Previous attempts to make it idiomatic didn't work well because to some extent the sizes would not be known in advance/would need to be known in advance.
At a minimum, the handling needs to be improved slightly with: unit tests for some of the basic functionality, some amount of diagnostics to allow investigations if things go wrong.
