BLTE (Block Table Entry) Compression/Decompression Library

BLTE is Blizzard’s compression and encryption format used throughout their content distribution system. This crate provides parsing and decompression capabilities for all BLTE modes.

§Archive Support

Blizzard’s CDN serves content as 256MB archive files containing multiple concatenated BLTE files. Use the archive module for handling these files.
