C-style printf/sprintf for JavaScript

The `format` package (current version 0.2.2) provides `printf`, `sprintf`, and `vsprintf` functions for JavaScript, emulating the string formatting capabilities found in the C standard library. It supports a range of format specifiers including `b`, `c`, `d`, `f`, `o`, `s`, `x`, and `X`, along with precision control for floating-point numbers. The package was last updated in 2014 and explicitly targets Node.js versions 0.4.x and above, as well as web browsers by direct script inclusion. Its core value proposition was to offer a familiar C-style formatting API in JavaScript environments. Due to its age and lack of maintenance over the last decade, it should be considered an abandoned project, potentially incompatible with modern JavaScript ecosystems and lacking critical updates for security or compatibility.
