flat violins and facet scales

[dmaltschul]

Hello,
I have found that the geom_flat_violin() function doesn't allow one to free scales in facet_wrap() or facet_grid(). I understand that using coord_flip() may also cause this problem with facet scales, though removing coord_flip() from the plot did not solve the problem and I was able to narrow it down to geom_flip_violin().

I also have run into this issue. Adding this functionality would be incredibly useful!
