H264 Profile Level ID Utility

The `h264-profile-level-id` package is a TypeScript utility designed to accurately process H.264 `profile-level-id` values, which are critical in WebRTC SDP negotiation. It is based on the robust C++ implementation found in Google's `libwebrtc` project, ensuring compatibility and correctness with widely used WebRTC stacks. Currently at version `2.3.2`, the library maintains active development, aligning with updates in the WebRTC ecosystem. Its primary differentiator is its direct lineage from `libwebrtc`, providing a reliable, type-safe API for parsing, serializing, and comparing H.264 profile and level identifiers, including specialized functions for SDP parameter handling. It supports Node.js environments `>=20` and ships with comprehensive TypeScript types, making it suitable for modern JavaScript and TypeScript projects that interact with H.264 video codecs.
