Assessment per km2

[david-beauchesne]

At the moment, the code assumes that the projection is in meters and that cells are 1km2. This does not make sense in the long run and we should use the package units to deal with units.

dplyr::mutate(area = sf::st_area(geo)) |>
dplyr::mutate(area = units::set_units(area, km^2))
