CRAN v0.4.1

Minor changes

• dodgr_flows_aggregate() now has a pairwise parameter, to enable flows to be aggregated only along paths connecting each pair of from and to points. Thanks to @chinhqho via #229
• Update igraph::get.edgelist -> as_edgelist (#229) to suppress warnings from igraph conversion functions.
• Minor tweak to bundled src/concaveman to remove CRAN warning from new gcc 14.x (#235)
