Simple TSV and CSV Parser/Converter

The `tsv` package provides a lightweight, dependency-free solution for converting between JSON and Tab-Separated Values (TSV) or Comma-Separated Values (CSV) formats. Currently at version 0.2.0 (published 13 years ago), this library is explicitly marked by its author as unmaintained and unsuitable for production environments due to its synchronous parsing, inefficiency with large datasets, and vulnerability to non-sanitized input data. It was originally designed for efficiently serving small datasets to client-side visualization libraries like D3.js. Given its age and the author's deprecation notice, it lacks modern features like asynchronous processing, robust error handling for malformed data, and native ESM support, common in contemporary data parsing libraries.
