/**
 list of iso-639-1 language codes to extract from osm tags

 this file is nessesary due to the free-tagging nature of
 osm. @see ./test/fixtures for an example list of tags
 contained in the planet file (sourced from taginfo)

 some common keys we need to defend against:
 'name:ဗမာ', 'name:<阪神電鉄>', 'name:*'

 Here is an example of the usage.
 All these tags might appear on the same element:

  name=Irgendwas        (the default name, used locally)
  name:en=Something     (the name in English)
  name:el=Κάτι          (the name in Greek)
  name:de=Irgendwas     (the name in German)
  name:pl=Coś           (the name in Polish)
  name:fr=Quelque chose (the name in French)
  name:es=Algo          (the name in Spanish)
  name:it=Qualcosa      (the name in Italian)
  name:ja=何か          (the name in Japanese)
  name:ko=뭔가           (the name in Korean)
  name:ko_rm=Mweonga    (the name in Romanised Korean)

  @note: 'ko_rm' is present in the osm database but not supported
  by pelias due to it not being listed in the ISO specification.
