Module normalization 

Audio normalization with RMS targeting and peak limiting.

This module provides intelligent audio level normalization that:

• Targets a configurable RMS level (e.g., -20 dBFS)
• Prevents clipping with hard peak limiting at ±1.0
• Enforces maximum gain ceiling to avoid over-amplification
• Handles silence and very quiet audio gracefully

Example

use speech_prep::preprocessing::Normalizer;

let normalizer = Normalizer::new(0.5, 10.0)?;
let quiet_audio = vec![0.1f32; 1000];
let normalized = normalizer.normalize(&quiet_audio)?;
