ddn.compressor.utils

Compression utility functions.

This module provides common helper functions for compression tasks, including format detection, size estimation, and file convenience helpers.

Format detection and size estimation work purely with format metadata, while file convenience helpers provide simple file-to-file compression and decompression operations using the provider system.
