Vonage HTTP Client for Python

The `vonage-http-client` is a foundational Python HTTP client library for interacting with Vonage APIs. It provides low-level request building and authentication mechanisms, supporting API key/secret and JWT-based authentication. While primarily an internal dependency of the higher-level `vonage` Python SDK, it can be used directly for specific API interactions. The current version is 1.5.1, and it has a relatively stable release cadence, with updates typically coinciding with major SDK changes or specific HTTP client enhancements.
