windfarmGA 4.0.0

• Depends on R 4.1.0
• Removed package dependencies rgdal and rgeos
• Replaced dependency raster with terra
• Moved dependencies foreach, parallel, doParallel, elevatr to Suggests
• 3D-circle intersection calculation. Especially relevant if the terrain model is activated.
• Fix grid_area and hexa_area functions for sf-1.0 and s2
• Removed most visibility functions in favor of terra::viewshed
• Removed the function windfarmGA, as it was redundant and just difficult to test.
• Changed most cat() and print() calls with message()
• Reset old par settings

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.
