Computation of CRPS
This routine computes the continuous ranked probability score (CRPS) and its decomposition into uncertainty and resolution: CRPS = RELI + RESOL. In addition the uncertainty is computed. A perfectly reliable system gives RELI=0. An informative system gives RESOL << UNCERT.
The computation follows H. Hersbach, Weather and Forecasting 15(2000) 599-570. Here, RESOL is equivalent to CPRS_pot.
