Lightweight CLI Argument Parser

getarg is a lightweight and fast command-line argument parser designed for Node.js applications, currently at version 0.0.5. It focuses on providing a simple API for defining, parsing, and validating CLI arguments, including support for required parameters, basic type enforcement (string, number, json, any), aliases, custom help messages, and inter-argument dependencies. Unlike more comprehensive CLI frameworks such as Yargs or Commander, `getarg` prioritizes minimalism and directness, making it suitable for smaller scripts or cases where extensive feature sets are not required. As a pre-1.0 release, its API might still evolve, though the core functionality is designed for quick integration into Node.js projects requiring basic argument handling.
