Possible error when using archives with .tar.<extension>

[lstocchi]

          If the value of `archive` is `archiv.tar.bz2`, archiveType would not be correctly set.

I would have suggested to use path.basename instead of replace:

let archiveType = path.extname(archive);
if (path.extname(path.basename(archive)) === '.tar') {
  archiveType = '.tar' + archiveType;
}
