Multipart and Tar utilities for Web Streams

multitars is a JavaScript library providing memory-efficient parsing and production of Tar archives and `multipart/form-data` bodies, built entirely on the Web Streams API. It is currently at version 1.0.0, indicating a stable API after several pre-1.0.0 releases that focused on performance and feature additions. The library's core differentiator is its ability to process arbitrarily-sized stream data without buffering it in full, making it ideal for environments like serverless functions, browsers, and Node.js applications that require efficient handling of large binary data streams. It aims to offer Tar format support comparable to `node-tar`, including PAX headers, and provides both parsing and streaming utilities for both formats.
