[page 1] As user, I'd like to have access to ICES division on the leaflet map

[statnmap]

Validation

• ICES Division are presented on map on page 1
• I can choose to hide them

Tech

• Create a spatial dataset in the database
• Write the SQL code to read it
• Use get_data_continent_m() as an example of how to do it
• Add it as pre-load in the "dev/run_dev.R" + in "app.R"
• Add the layer in the tm_draw()
