Title: Update to xxhash r39, which fixes the alignment errors

Errors were found with `-fsanitize=undefined`.

Dirk,

This updates to [xxHash/r39](https://github.com/Cyan4973/xxHash/releases/tag/r39) which fixes the alignment issues. This was only released 3 days ago, so the initial implementation I used did not have these fixes.
