This development introduces a new parameter return_mean into the functions RPS.R and CRPS.R. This parameter is a logical indicating whether to return the temporal mean of the score or not. When TRUE the temporal mean is calculated, when FALSE the time
dimension is not aggregated. The default is TRUE.
This development is required for the scorecards in SUNSET, since the dimension syear is needed for these metrics. See merge request for more details: sunset!120 (merged)
