Use new modular flow routing interface for D8 #421

Description

@wkearn

TopoToolbox/libtopotoolbox#225 introduces a new interface for flow routing. The steps for flow routing with D8 and least cost auxiliary topography carving are now:

  • Fill the DEM with fillsinks
  • Run D8 flow routing on the filled DEM (flow_routing_d8_directions followed by flow_routing_d8_weights)
  • Identify flats, compute GWDT as before
  • Compute the flow directions on flats using the GWDT (resolve_flats_lcat followed by resolve_flats_lcat_weights)
  • Merge the D8 and LCAT flow directions (edgeset_merge)
  • Compute the topologically ordered edge list (flow_routing_tsort)
