Changing color of nanoplot boxplot

[bensoltoff]

Is there a way to change the color of a nanoplot of "boxplot" type? Using the example from the documentation the boxplot seems to use #70BCF9FF as the default stroke color for the line box components. But I don't see any specific arguments in nanoplot_options() for modifying boxplot components. I tried using data_line_stroke_color and data_point_stroke_color, but they have no effect.
