docs: Slugify a path, maintaining a map with the previously slugified paths.
  
      The path table is used to prevent slugified names from collisioning,
      using the `iso_name_increment` function to deduplicate slugs.
  
      Example:
          >>> path_table = {'/': '/'}
          >>> iso_path_slugify('/ébc.txt', path_table)
          '/_BC.TXT'
          >>> iso_path_slugify('/àbc.txt', path_table)
          '/_BC2.TXT'
