- Introduced arjz.h header file with function declaration for buffer decompression. - Updated library.h to include ARJ and ARJZ decompression method declarations. - Added test cases for ARJ decompression methods (Method 1 to Method 4) in arj.cpp. - Implemented test cases for ARJZ decompression methods in arjz.cpp, including default and custom extended DEFLATE. - Copied necessary binary test data files for ARJ and ARJZ methods into the tests/data directory.
