wrk Load Test Tool Wrapper

The `wrk` Node.js package serves as a wrapper for the popular `wrk` HTTP benchmarking command-line tool. It enables developers to programmatically execute load tests and parse the output directly within a Node.js environment, simplifying the integration of performance testing into applications or CI/CD pipelines. This package allows configuration of `wrk` parameters such as threads, connections, and test duration, and then processes the `wrk` tool's raw output into a structured JavaScript object containing detailed performance metrics like requests per second, latency statistics, and transfer rates. Currently at version 1.2.1, the package was last published in September 2020, indicating it is no longer actively maintained. Its primary utility lies in abstracting the `child_process` execution and output parsing, but it critically depends on the `wrk` CLI tool being pre-installed on the system and accessible in the PATH.
