Rambunctious Koala

A few changes and a few bugfixes:

• Fixed bug where hash output the wrong number of hashes
• Vowpal wabbit vectors now include the number of times each hash occurs as the feature value. The key is still the hash.
• hash now outputs VW vectors using the -w flag.
• Added a feature to merge a sketch (i.e. generate sample-level sketches and VW-vectors) to stream and hash using the -m flag.
• Fixed a bug with inserting into a min-heap that happened sometimes in hash

Rigged Karma

This release brings full hash functionality to export sketches as JSON. It fixes a bug with the -D / --diff argument in stream and classify which caused reads to never be flagged as failing. There are minor improvements in stability at the cost of a tiny bit of performance.

Rogue Kraken

This is the first 'release' of rkmh. It brings streaming read labeling, improved speed, better thread safety, and basic hash output. Given that it's still a 0.x.x release, expect it to be rough around the edges in some of the less-polished areas. If you break it, please post about it in the github!
