v23.1.0

[sourcefrog]

• Switched to CalVer versioning.

• New: Support for storing, restoring, and listing Unix owner, group, and permissions.
  Thanks to @believeinlain.

• Fixed: --exclude /a now also excludes everything under /a from listing, diff, restore, etc.
  (Previously you would have to write /a/**.)

• Fixed: validate should not complain about GC_LOCK or .DS_Store files in the archive directory.
