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

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.

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!
