I wrote this to add components to compress and expand ranges.
Highlights:
1. doesn't do any memory allocation
2. can handle arbitrarily large sets of data
3. it's lazy
4. takes an InputRange, and outputs an InputRange
Comments welcome.
I may have misunderstood something, but the code does not
implement LZW (a variant of LZ78), but a variant of LZ77 (i.e.
deflate/ZIP).
See https://en.wikipedia.org/wiki/LZ77_and_LZ78
