Surface covered by a LAS* object. For LAS point clouds it is computed based on the number of
occupied cells, or on the area of the convex hull of the points when the density is too low. For a
LAScatalog it is computed as the sum of the bounding boxes of the files. For overlapping tiles
the value may be larger than the total area covered because some regions are sampled twice.
For a LASheader it is computed with the bounding box. As a consequence, for the same file
st_area applied on a LASheader or on a LAS can return slightly different values. st_area()
extends sf:st_area(), area() extends raster:area(). area() is provided for backward
compatibility.
