v0.1.17-devel

Features

1. Add a commitCb method to the callback-based API which allows committing asynchronously.
2. Pass assign/unassign functions to the rebalance callback in the promisified API, allowing the user to control the assignment of partitions, or pause just after a rebalance.
3. Remove store from promisified API and let the library handle all the stores.
4. Add JavaScript-level debug logging to the client for debugging issues within the binding.
5. Various fixes for performance and robustness of the consumer cache.
6. Remove consumerGroupId argument from the sendOffsets method of the transactional producer, and instead, only allow using a consumer.

Fixes

1. Do not modify RegExps which don't start with a ^, instead, throw an error so that there is no unexpected behaviour for the user (Issue #64).
2. Do not mutate arguments in run, pause and resume (Issue #61).
3. Fix a segmentation fault in listGroups when passing matchConsumerGroupStates as undefined.
