I attempted to use 7z/7zr for handling tar formats, but ran into issues because 7z requires unpacking compressed tar archives (like .tar.gz or .tgz) in two steps: first to decompress the gzip layer, and then to extract the tar archive. This would necessitate refactoring to manage intermediate files and decide when multiple unpacking steps are needed. For instance, both .tar.gz and .tgz require two steps, as they are effectively the same.

Additionally, it would require handling different combinations of compressed formats, such as .exe.gz. In such cases, the first step would be decompressing the .gz layer to access the underlying file (e.g., .exe). This logic applies to other combinations as well, where varying numbers of steps are needed depending on the file types. For example, .tar.gz requires two steps, while .exe.gz only needs one.

Since the main goal of this work is to remove the dependency on MSI, I decided to continue using tar.exe for decompressing tar files and leave the handling of these combinations for another PR.
