Allow `gt_sparkline` to plot multiple density curves in one plot

Is it possible to somehow plot multiple density curves in one plot using gt_sparkline? Something like this:

Hi @jorgesinval - this is a cool idea! However, it's not something I'm likely to incorporate as the core functionality is one row and one graphic. You can always "escape" out to using gt + gt::ggplot_image() if you'd like to embed custom graphics or combined graphics as you're intending.

Thanks!
