ENH: Save _MonteCarloPlots.all plots to disk #847
Description
Is your feature request related to a problem? Please describe.
The histograms generated by by MonteCarlo simulations (e.g. monte_carlo_simulation.plots.all()) cannot be saved because the function is missing a save boolean (like the ellipses function already has, e.g. monte_carlo_simulation.plots.ellipses(save=True)).
Describe the solution you'd like
Add save functionality to _MonteCarloPlots.all
Additional context
Other plots in RocketPy, e.g. _FlightPlots.linear_kinematics_data, have a filename parameter instead of a save boolean. Please consider whether it would make sense to adapt MonteCarlo-related plot functions to allow specifying the filename as well.
