Violin plots on table & column

[lars-reimann]

Is your feature request related to a problem?

Box plots offer a simplified visualization of the distribution that underlies the data. They might hide some important details, however (see this).

Desired solution

Add violin plots as a new visualization for tables and columns.

• Add a method violin_plots() -> Image to the TablePlotter. It should show violin plots in a grid for all numeric columns, similar to how box plots for an entire table work.
• Add a method violin_plot() -> Image to the ColumnPlotter.
• Support dark mode (see Dark mode for plots #798) by adding the appropriate parameter, as outlined in the linked issue.
