Develop interfacing specs verification

Hi @vtorralba @obellprat

Would you mind testing the UltimateBrier?
Should work with any of the 'type' BS, FairEnsembleBS, FairStartDatesBS, BSS, FairEnsembleBSS, FairStartDatesBSS and with any exp and obs anomalies from Ano() (lonlat, lat, lon, areave) that don't contain NA values.

CFU_BS is now included as BrierScore.
When selecting BSS type, $bss_res from BrierScore is returned.
When selecting FairStartDatesBSS type, $bss_gres from BrierScore is returned.
It is a pending issue to make sure these are the expected variables. Other available variables that BrierScore returns can be checked in ?BrierScore, just in case you want to check.
