Some language codes not recognized by iso639.Language.match()

Running codes.py yielded the following error:

For whatever reason, the iso639 module isn't recognizing some of the language codes from the wiktionary API. Someone should look into why this is, or maybe omit languages that don't have valid language codes.

I hadn't seen that fatal exception before. I think we should probably catch it and convert it to a warning. What do you think?

[sonofthomp]

Giving a warning sounds like a good idea. In place of iso639_lang = iso639.Language.match(wiktionary_code), I'm thinking something like:

try:
    iso639_lang = iso639.Language.match(wiktionary_code)
except iso639.language.LanguageNotFoundError:
    logging.warning(
        "Could not find language with code %s", wiktionary_code
    )

... so that in the case of gmw-cfr, the following is outputted:

codes.py WARNING: Could not find language with code gmw-cfr

[kylebgorman]

codes.py WARNING: Could not find language with code gmw-cfr

This proposal LGTM.

Closed in #499, I believe.
