Add robohash performance optimization

Browse Source 
- Add OptimizedRobohash class with directory caching and optimized file selection
- Integrate optimization into ivatar views for 2-6x performance improvement
- Add comprehensive tests covering functionality, pixel-perfect identity, and performance
- Add ROBOHASH_OPTIMIZATION_ENABLED configuration setting
- Maintain 100% compatibility with original robohash output

Performance improvements:
- Directory structure caching eliminates repeated filesystem scans
- Reduced natsort calls from 163 to ~10 per generation
- 2-6x faster generation times while maintaining identical image output
- Significantly improved concurrent throughput

Tests added:
- Functionality verification
- Pixel-perfect identical results with random email addresses
- Performance measurement across multiple configurations
- Integration testing with create_optimized_robohash function
