HTTP Header Parser

The `parse-headers` package is a lightweight utility designed to transform raw HTTP header strings into a JavaScript object. It is currently at version 2.0.6, with its last update occurring approximately one year ago (as of early 2024), indicating a slow release cadence and minimal active development. The library's core functionality involves parsing a multi-line header string, lowercasing all header names, and consolidating multiple instances of the same header into an array of values. It distinguishes itself by being a zero-dependency solution, making it ideal for environments where a minimal footprint is critical, such as older browser environments via Browserify or for basic XHR header processing. Unlike more comprehensive, RFC-strict parsers that handle structured field values, `parse-headers` offers a straightforward, object-based representation suitable for common, less complex HTTP header scenarios.
