Module progress 

Enhanced progress reporting for archive operations.

This module provides extended progress callbacks with support for:

• Cancellation signaling (return false to abort)
• Compression ratio tracking
• ETA calculation
• Rate limiting callbacks to reduce overhead

Example

use zesven::progress::{ProgressReporter, StatisticsProgress};
use zesven::{Archive, ExtractOptions};

let progress = StatisticsProgress::new();
let options = ExtractOptions::new().progress(progress);
archive.extract("./output", (), &options)?;
