Manage sf_hydro_regions object
Should we keep them as datasets or make a function that returns a different object depending on a 'territory' argument?
Currently, the package contains the following data sets:
sf_hydro_regions_gua
sf_hydro_regions_met
sf_hydro_regions_mtq
sf_hydro_regions_myt
sf_hydro_regions_reu
They could therefore be replaced by the following function:
get_sf_hydro_regions(territory = "Mayotte")
