Ternary UNet submission (PR #640) folder is in track_10min_16mb instead of track_non_record_16mb

[janwww]

PR #640 placed the 73.7M Ternary UNet folder under records/track_10min_16mb/,
but the README accepted it as a Notable Non-Record Run (not in the main leaderboard).
Non-record submissions should live in records/track_non_record_16mb/.
