GS1 Barcode Parser

The `gs1-barcode-parser-mod` library is an active fork designed for parsing the complex data structures found within GS1 barcodes. It provides a single function to decompose the raw string content of a GS1 barcode into an array of structured data elements, each identified by its Application Identifier (AI). This enables JavaScript applications to easily extract specific information such as GTIN, batch/lot numbers, expiration dates, and weights. The current stable version is 1.0.7. It's particularly useful in scenarios where barcode scanning devices provide a raw string, and the application needs to process this data for inventory management, point-of-sale, or logistics. Its key differentiator is its focused utility for GS1 standards, though it's important to note it's based on the GS1 'Version 14, Issue 1, Jan 2014' specification, which might not cover the absolute latest revisions.
