TOON Format for Python

TOON (Token-Oriented Object Notation) is a compact, human-readable data format designed for LLM prompts to reduce token usage by 30-60% compared to JSON. It achieves this by eliminating redundant punctuation and using a tabular format for uniform data structures. The Python implementation, currently in beta (v0.9.0-beta.1), provides encoding and decoding functionalities, aiming for full compliance with the TOON specification.
