Add `TableDataSavingCallback`

[LasNikas]

This is to save table data only for a specific time range save_interval. The rows in the table are the function values and the columns are the evaluations.

hydrostatic_water_column_2d.jl with the following extra_callback

interpolated_density(v, u, t, system) = nothing
function interpolated_density(v, u, t, system::TrixiParticles.FluidSystem)
    n_particles_xy = round(Int, 1.0 / system.initial_condition.particle_spacing)

    values = interpolate_line([0.5, 0.0], [0.5, 1.0], n_particles_xy, semi, system,
                              v, u; endpoint=true, cut_off_bnd=true)

    return values.density
end

pos = collect(LinRange(0.0, 1.0, round(Int, 1.0 / fluid_particle_spacing)))

extra_callback = TableDataSavingCallback(; dt=0.02, save_interval=10, 
                                         start_at=0.90, # condition is `true` if `t >= start_at` 
                                         axis_ticks=Dict(interpolated_density => pos),
                                         interpolated_density=interpolated_density)

The plot shows the density evaluated at every dt starting at time t=0.9
