some two-letter language codes don't seem to be recognised

[jonorthwash]

The following two-letter language codes seem not provide localisations for their three-letter-coded language names:

• ln for lin
  https://github.com/apertium/apertium-apy/blob/master/language_names/scraped-cldr.tsv#L7876

• lv for lvs
  https://github.com/apertium/apertium-apy/blob/master/language_names/scraped-cldr.tsv#L8296

• ms for zlm
  https://github.com/apertium/apertium-apy/blob/master/language_names/scraped-cldr.tsv#L8961

See also #152.

Probably because they're missing in https://github.com/apertium/apertium-apy/blob/master/apertium_apy/utils/__init__.py#L12.
