Bump tar dependency

[confused-Techie]

While I intended to bump all dependencies in #7, unfortunately bumping the tar dependency was rather involved, as that code base has seen lots of changes in the meantime.

In this PR when bumping tar to the latest I had to make a few code changes:

• tar now gives us strings instead of string-like numbers for types.
• Invoking the Parse function directly no longer works, the modern equivalent is t().
• We expect errors on invalid files, requiring the use of the strict option, as tar now automatically recovers from these situations.
• Accessing the path and type values are now at the root of an entry object

You'll notice I was very careful to not touch any of the specs here, so we can be confident in these code changes keeping the exact same outside behavior.

Sorry my bad, didn't mean to include all other bumps here, suppose that means that #7 should likely be merged on it's own first, then this one can be fully evaluated of it's own merit.

I've reviewed #7 just now, the remaining changes focused on tar look good here, nothing too too crazy. Small diff, IMO.

Indeed, this is nice to see! LGTM. 👍
