Per-mode stop clustering thresholds

Browse Source 
Rail stations get generous thresholds to merge all platform/entrance
duplicates; bus stays conservative:
  metro: 200m    -> 91 stops -> 44 markers (0 duplicates)
  s_tog: 400m   -> 76 stops -> 30 markers (0 duplicates)
  regional: 500m -> 27 stops ->  9 markers (0 duplicates)
  bus: 100m      -> 1610 stops -> 781 markers

stop_cluster_m is now a dict keyed by mode in styling.yaml.
