Brightspace Auth Token Provisioning

The `brightspace-auth-provisioning` library facilitates the creation and assertion of access tokens against a Brightspace authentication service. It abstracts the complexities of token generation, allowing developers to provision tokens with specific claims such as scopes, tenant IDs, user IDs, impersonator IDs, and Caliper FSIDs. The current stable version is `9.0.1`, which requires Node.js version `20.x` or higher. The package sees active development with major versions released periodically (e.g., v7, v8, v9) and more frequent patch and minor releases. Its key differentiator is its tight integration with the Brightspace authentication ecosystem, providing a specific API for generating tokens that adhere to Brightspace's assertion requirements, including a flexible `keyLookup` mechanism for signing keys and support for caching mechanisms.
