This PR does not really solve an open issue, but does make GeomSf more consistent with other geoms.
Briefly, sf_grob() was a wrapper for sf::st_as_grob() that did two things that are usually handled by Geom classes.
It removed missing data, which is usually handled by Geom$handle_na(), and wrangles the graphical parameters for a grob, which is usually done in Geom$draw_panel().
This PR divides these two responsibilities to the appropriate places in the class.
