Module polyblep

PolyBLEP and PolyBLAMP anti-aliasing for band-limited waveform generation.

This module provides polynomial corrections to eliminate aliasing artifacts from discontinuous waveforms (sawtooth, square, pulse) and slope discontinuities (triangle).

PolyBLEP (Polynomial Band-Limited Step) smooths step discontinuities by applying a polynomial correction near the transition point. PolyBLAMP (Band-Limited rAMP) is the integrated form, used for slope discontinuities.

All functions are generic over the Sample trait for efficient f32/f64 processing.
