Restrict path traversal on TarArchive extraction

[piksel]

Prevents files from being written outside of the destination directory when extracted using TarArchive.ExtractContents.
Basically the Tar version of #235

Attempting to extract a file that has a path traversing outside of the destinationDirectory will throw and InvalidNameException unless explicitly overridden:

tarArchive.ExtractContents(destinationDirectory, allowParentTraversal: true);
