V0.6.2

Version 0.6.2

This release includes several improvements to the caching mechanism, new features for testing, and a version bump.

Implemented caching mechanism across various bot components, including QueryBot, SimpleBot, and StructuredBot. Added a new cache module and updated dependencies to include diskcache. (b7d2b32, Eric Ma)
Added deterministic mock response generation for tests. Imported hashlib to use for generating hash-based mock responses and created a new function generate_mock_response to produce unique responses. (4a49925, Eric Ma)

Improved caching mechanism in SimpleBot methods by adding ignore={0} to @cache.memoize() in key methods to ignore "self" positional arg. (621e8e9, Eric Ma)

Refactored caching in SimpleBot methods, removing caching from stream_panel and stream_api methods and adding caching to generate_response method. (f35bab2, Eric Ma)
Refactored caching in bot classes, removing redundant caching decorators from QueryBot and StructuredBot and adding caching to various stream methods in SimpleBot to optimize performance. (282efbc, Eric Ma)
Refactored test_simple_bot_stream_stdout to use hypothesis strategies more efficiently, replacing multiple given decorators with a single one using st.data() and using st.tuples to draw system_prompt, human_message, and mock_response together. (8b56779, Eric Ma)
