CDC File Transfer

Article note: My brain was looking at it trying to fit "CDC"=Centers for Disease Control? Control Data Corporation? Cult of the Dead Cow? Composite Device Class? But no, this overload is "Content Defined Chunking," which smells sort of like a more sophisticated rsync style rolling hash with variable block size. I think the got project is a more general tool with the same basic model, but this is oddly proven code since it was tooling for the now-expensively-failed Stadia infrastructure. It's a neat direct application of a neat algorithm.
