NetworkForge 0.10.0

Added

• Standalone networks: networkforge build --no-osm (Python:
  build_network(None, lines, standalone=True)) builds a network from the
  custom lines alone, with no OpenStreetMap, no area and no download.
  Tags, presets and checks work as usual. --join-at crossings (default)
  joins lines wherever they cross; --join-at vertices only where they
  share a vertex, for data that already has a vertex at every junction.
  A warning names the features outside the largest connected piece.
  networkforge info reports standalone and join_at.
• Line ends that stop within the snap distance of each other without
  touching now share one node (also when adding lines to OpenStreetMap).

Changed

• The package description and README now say what the tool has become:
  building and editing street networks, not only adding proposed lines.
• build no longer requires --extent / --bbox on the command line
  when --no-osm is given (it still does otherwise; exit code 2).

Fixed

• An area or layer in a world-wide projection such as Web Mercator
  (EPSG:3857) was measured in that projection, where a metre on the map
  is not a metre on the ground (79% too long in Scotland): lengths in the
  GeoPackage and the snap distance were wrong. A local UTM zone is now
  used unless the CRS is a regional one.
