Changed Bench Eval to report metrics correctly by split. Added total accuracy and renamed previously used bench_accuracy to bench_average_accuracy. (#512)

* Added "eval_" prefix

* Added total bench accuracy and renamed the previous one to bench_average_accuracy. Changed naming to use bench_split instead of always using eval_ prefix.
