feat: migrate to reed-solomon-simd only implementation

- Remove reed-solomon-erasure dependency and all related code
- Simplify ReedSolomonEncoder from enum to struct with SIMD-only implementation
- Eliminate all conditional compilation (#[cfg(feature = ...)])
- Add instance caching with RwLock-based encoder/decoder reuse
- Implement reset mechanism to avoid unnecessary allocations
- Ensure thread safety with proper cache management
- Update documentation and benchmark scripts for SIMD-only approach
- Apply code formatting across all files

Breaking Changes:
- Removes support for reed-solomon-erasure feature flag
- API remains compatible but implementation is now SIMD-only

Performance Impact:
- Improved encoding/decoding performance through SIMD optimization
- Reduced memory allocations via instance caching
- Enhanced thread safety and concurrency support
