Feature request: Option to create subfolders of subfolders.¡ in kml_layer.SpatialPoints

[AlvaroMCMC]

Hi,

Currently we have this.

kml_layer.SpatialPoints(puntos_sfc, subfolder.name = "subfolder_level1", points_names = puntos_sfc$NAME, colour = "red",
                        shape = 'http://plotkml.r-forge.r-project.org/3Dballyellow.png',
                        LabelScale = 0.8)

There could be and option in subfolder.name to write "subfolder_level1/subfolder_level2/subfolder_level3", so in Google Earth this would appear like this, and this won't some limit of subfolders.

Thanks in advance.
