Function which returns the tile IDs of the Sentinel-2 tiles which overlap a provided extent.
tiles_intersects(extent, all = FALSE, out_format = "id", .s2tiles = NULL)
logical: if TRUE, all the tiles overlapping the extent are provided; if FALSE (default), unnecessary tiles are skipped. Unnecessary tiles are tiles which overlaps the extent for an area already covered by another tile. In case the extent is all included in an overlapping area, only one of the two candidate tiles is returned (the first in alphabetical order).
character: if "sf", the spatial object of the overlapping tiles is returned; if "id" (default), a character vector with the tile IDs.
