Azure Namespace Package

The `azure-nspkg` library is an internal Microsoft Azure Namespace Package, currently at version 3.0.2. Its original purpose was to provide the top-level `azure` namespace for older Azure SDKs. It is rarely needed directly in modern applications as individual Azure SDK client libraries (e.g., `azure-storage-blob`, `azure-eventhub`) now manage their own namespaces and dependencies, making `azure-nspkg` largely obsolete for new development.
