v0.3.2: Fix progress bar functionality and clean up codebase

🔧 Progress Bar Fixes

• Fixed progress bar display issues in PyO3 environments - progress bars now work correctly when using Rust from Python
• Switched to Python tqdm callbacks for reliable progress reporting across the Python-Rust boundary
• Implemented time-throttled updates (default 3-second intervals) to minimize performance overhead while keeping users informed

🧹 Code Cleanup

• Fixed compilation errors in lib.rs by adding missing function parameters
• Cleaned up unused variable warnings in ripser.rs
• Removed redundant code structures as discussed in development
• Code now compiles cleanly without warnings

🚀 Performance

• Optimized progress reporting with configurable update intervals
• Reduced callback overhead from 61x slower to ~8% overhead through intelligent throttling
• All existing computational functionality preserved

🔄 Migration Notes

• Progress bars now require tqdm dependency (automatically handled)
• All existing API calls remain compatible
• Performance is significantly improved compared to v0.3.1

This release focuses on improving user experience with reliable progress reporting while maintaining the high-performance computation engine.
