Node-OPCUA Standard NodeSets

The `node-opcua-nodeset-ua` package is a core component of the `node-opcua` SDK, providing the standard OPC UA NodeSet XML definitions. These definitions are essential for building OPC UA servers that expose a semantically rich address space conforming to the OPC UA Unified Architecture specification. As part of the highly active `node-opcua` monorepo, it receives frequent updates, typically bi-weekly, aligning with the project's 'Perpetual Beta' model. The current stable version is 2.169.0. Key differentiators for the `node-opcua` ecosystem, including this module, include its pure Node.js implementation, extensive TypeScript support, and a focus on industrial IoT (IIoT) and Machine-to-Machine (M2M) communication. It allows developers to load standard and custom information models into an OPC UA server's address space for robust data exposure.
