Feature: enable color sea / oceans option - hc_add_series

Hi,
I don't think there is any option to color water bodies, like oceans and seas, in maps yet.
I'm using hc_add_series_map and hc_add_series, but I suppose this should also work in hcmap.
Basically it should be a background color for the map, but not for the chart.
You can't use hc_chart(backgroundColor = "lightblue")
because that also colors titles and legends for example.
Perhaps there should be a backgroundColor in hc_add_series_map?
(I cant provide a world map dataset here so I cut it to ISR only for the reproducible example.
Please consider this shape is an island and everything around it should be blue.)

hc_add_series(

hc_title(

or hcmap but I'm personally not using hcmap.
