v1.4.0

Mainly improvements to the llama.cpp engine in this release.

Improvements

• Update the LlamaCppEngine to not use the Llama 2 prompt pipeline by default. Prompt pipelines must now be explicitly passed.
• The LlamaCppEngine will now automatically download additional GGUF shards when a sharded model is given.
• Added ChatTemplatePromptPipeline.from_pretrained to create a prompt pipeline from the chat template of any model on the HF Hub, by ID.
• Added examples and documentation for using DeepSeek-R1 (quantized).

Fixes

• chat_in_terminal_async no longer blocks the asyncio event loop when waiting for input from the terminal.
• Fixed the LlamaCppEngine not passing functions to the provided prompt pipeline.
