- Implemented ace_decompress_v2 and ace_decompress_v20_block functions for handling ACE v2 (blocked) decompression. - Added ace_decompress_lz77 function for ACE v1 (LZ77) decompression. - Updated library.h to declare new decompression functions. - Created unit tests for ACE v1 and v2 decompression, validating output against expected CRC32 checksums. - Included necessary binary test data for ACE v1 and v2 formats. - Refactored library.c to improve include order and reduce redundancy in function definitions.
