devel/py-hishel: Add py-hishel 0.0.25

Hishel is a library that implements HTTP Caching for HTTPX and HTTP Core
libraries in accordance with RFC 9111, the most recent caching specification.

Features:

• Persistence: Responses are cached in the persistent memory for later use.
• Compatibility: It is completely compatible with your existing transports or connection pools, whether they are default, custom, or provided by third-party libraries.
• Easy to use: You continue to use httpx while also enabling web cache.
• Smart: Attempts to clearly implement RFC 9111, understands Vary, Etag, Last-Modified, Cache-Control, and Expires headers, and handles response re-validation automatically.
• Configurable: You have complete control over how the responses are stored and serialized.
• From the package:
  • Built-in support for File system, Redis, SQLite, and AWS S3 backends.
  • Built-in support for JSON, YAML, and pickle serializers.
• Very fast: Your requests will be even faster if there are no IO operations.
