NULL if valid. Error otherwise

Examples

# compatible time types
casteval:::validate_fcst_obs_pair(
  create_forecast(data.frame(time=1:10, val=11:20)),
  data.frame(time=101:110, val_obs=111:120)
)

# incompatible time types
try(casteval:::validate_fcst_obs_pair(
  create_forecast(data.frame(time=1:10, val=11:20)),
  data.frame(time=lubridate::ymd("2024-01-01"), val_obs=5)
))
#> Error in casteval:::validate_fcst_obs_pair(create_forecast(data.frame(time = 1:10,  : 
#>   observations time type must match forecast time type
