This pull request improves the TODO section in the Minisketch README.md by:
- Adding detailed explanations for each planned improvement:
- Explicit formulas for higher-degree polynomials
- Subquadratic multiplication and modulus algorithms
- Half-GCD algorithm implementation
- Incremental decoding interface
- Platform-specific optimizations beyond x86
- 32-bit host optimizations
- IBLT/Hybrid approaches
- Introducing implementation priorities to guide future development efforts:
- Prioritizes ARM optimizations for mobile/embedded use
- Highlights incremental decoding as high value for practical applications
- Orders remaining improvements by complexity and expected performance gains
These enhancements make the roadmap clearer for potential contributors and provide better context about the technical goals of the project. The detailed explanations help developers understand the purpose and potential impact of each planned improvement.
