Subject: [PATCH] (FSRS) Improve presentation of log loss and RMSE (#2805)

* (FSRS) Improve presentation of log loss and RMSE

The number of decimal places in log loss have been increased from 3 to 4. Can help in better comparison of weights especially when the log loss with both are same up to 3 places of decimal. Also makes it consistent with the Python optimizer.

RMSE has been expressed in percent, making it easier to interpret.

* Fix formatting
