PublicationPlots do not check for non-finite data

Thanks for the suggestion.

We'd need to check the finiteness in

SDDP.jl/src/visualization/publication_plot.jl

Lines 16 to 17 in 6609655

 stage_data = stage_function.([data[stage] for data in dataset]) 
 output_array[:, stage] .= Statistics.quantile(stage_data, quantiles) 

But I think we should still accept NaN. So just +-Inf.
