3.0.0

• The dependencies sp, spatstat were removed and replaced by sf. All spatial outputs are now Simple Features. A Shapefile Polygon can still be passed as input to genetic_algorithm / windfarmGA, but more underlying functions now require the Polygon to be of type Simple Feature.
• The functions grid_area & hexa_area are now calculated with sf::st_make_grid.
• The new dependency elevatr has been added because it provides elevation data with a higher resolution compared to raster::getData.
• Several dependencies that are not essential for the algorithm were moved to Suggests.
• Bugfix for the calculation of the visibility analysis. #17
• The viewshed parameter h1 can now also be a numeric vector with different height offsets. #18
• The grid_area argument resol changed to size.
• The arguments for get_dist_angles have changed to match the arguments of turbine_influences.
