Parses the 'iloc' box in ISO Base Media File Format (used by HEIC/AVIF). Implements security bounds on the number of extents and validates sizes to prevent memory exhaustion attacks. This is a self-contained, reusable component for any project needing to extract item locations from BMFF files. It demonstrates non-obvious skill in binary format parsing with security constraints.

A collection of general-purpose utility functions isolated from internal dependencies. Includes `decompress()` with support for custom brotli/deflate and a `maxDecompressedSize` guard, prototype-safe `objectAssign` and `setProperty`, platform-agnostic string extraction from DataView, a `pushMetadataBlock` pattern for emitting byte-range metadata, and browser/Node detection helpers. These functions could be extracted into a separate project for any application dealing with binary data and decompression.

Implements configurable tag filtering based on metadata groups and individual tag names or IDs. Works with `includeTags` and `excludeTags` options to selectively retain or remove metadata fields. The logic is self-contained (depends only on `tag-filter-config.js` for parsing configuration) and could be reused in any metadata extraction pipeline that needs flexible field selection. Demonstrates a clean separation of configuration from application logic.
