Fixes #796
hvplot.save
was an alias forholoviews.util.save
except that hvPlot sometimes creates Panel objects which the HoloViews function couldn't save. So we delegate to<pn_obj>.save
. I also thought about just raising a clear error message but thought it'd make everyone's life simpler if it just worked directly. The real fix would be for hvPlot to no longer create Panel objects, but that's another issue.
