Added an include_grid_cell argument to make_2d_grid() that
makes the function return columns with the center coordinates
(lon_plot, lat_plot) of each grid cell prior to intersecting
with the user-provided sf object (passed to obj argument).
Centroids for intersected grid polygons are still returned by
the function for use in spatial analyses and index production
(e.g. VAST, sdmTMB) because they are the center of grid cells
after intersecting with stratum shapefiles. The centroid prior
to intersection is more useful for plotting gridded data with-
out prior transformation.
