Domain

Overview

This merge adds a few changes in response to the domain review. In summary, these are:

• Basins are now built from upstream to downstream
• Fixed data properties for exported basins
• Added conda installation
• Improved DEM conditioning
• watershed.network now returns pixel centers, rather than upper-right corners

Notes for Reviewer

I'd suggest focusing on the following points:

• The environment.yml file (this adds a conda install)
• pfdf/raster.py
  • Renamed dx and dy to width and height (lines 225-237)
• pfdf/segments.py
  • Build outlet basins from upstream to downstream (lines 1167-1168)
  • Enable data properties for basins (lines 2436-2440 and 2455-2459)
• pfdf/watershed.py
  • Improved DEM conditioning by using -Inf fill values instead of NaN (lines 130-137)
  • Record pixel centers, rather than corners (lines 545-547 and 554-555)
