Miha Kralj 3ed35322a5 Add TRIMA implementation and benchmarks; optimize WMA with SIMD
- Introduced `TrimaVector` class for multi-period Triangular Moving Average (TRIMA) calculations, optimized for SIMD.
- Implemented last-value substitution for invalid inputs in TRIMA.
- Added methods for calculating TRIMA for entire series and individual updates.
- Enhanced `Wma` class with periodic resync to prevent floating-point drift and introduced SIMD optimizations for performance.
- Updated benchmark suite to include TRIMA calculations alongside existing SMA, EMA, and WMA benchmarks.

Miha Kralj 5c1fb18520 Implement Weighted Moving Average (WMA) and Multi-Period WMA (WmaVector) classes with O(1) update complexity
- Added Wma class for calculating the Weighted Moving Average with detailed documentation and optimized performance using dual running sums.
- Introduced WmaVector class to handle multiple WMAs simultaneously, supporting batch calculations and real-time updates.
- Implemented last-value substitution for handling invalid inputs (NaN/Infinity) in both classes.
- Created comprehensive unit tests for Wma and WmaVector to ensure accuracy and reliability of calculations.
- Updated documentation to include usage examples, mathematical foundations, and performance characteristics.
