`hdr_value_at_percentile()` is part of the Hdr_Histogram library used when generating `latencystats` report. There's a pending optimization for this function which greatly affects the performance of `info latencystats`. https://github.com/HdrHistogram/HdrHistogram_c/pull/107 This PR: 1. Upgrades the sources in _deps/hdr_histogram_ to the latest Hdr_Histogram version 0.11.5 2. Applies the referenced optimization. 3. Adds minor documentation about the hdr_histogram dependency which was missing under _deps/README.md_. benchmark on my machine: running: `redis-benchmark -n 100000 info latencystats` on a clean build with no data. | benchmark | RPS | | ---- | ---- | | before upgrade to v0.11.05 | 7,681 | | before optimization | 12,474 | | after optimization | 52,606 | Co-authored-by: filipe oliveira <filipecosta.90@gmail.com>
