Josh Hawn a7aa2c8ad2 Finalize TarSum Version 1 w/ refactor
The current Dev version of TarSum includes hashing of extended
file attributes and omits inclusion of modified time headers.

I refactored the logic around the version differences to make it
more clear that the difference between versions is in how tar
headers are selected and ordered.

TarSum Version 1 is now declared with the new Dev version continuing
to track it.
