Language identification based on fasttext (lid.176.ftz https://fasttext.cc/docs/en/language-identification.html).
Python3.8, 3.9 only -- there seem to be some problems with python
The `lid.176.ftz` file is licensed under Creative Commons Attribution-Share-Alike License 3.0 and is not part of this module. It is automatically downloaded from its external origin on the first run of this module.
This module attempts to immitate the follow two features of `langid`
* langid.classify: fastlid
* langid.set_languages(langs=[...]): fastlid.set_languages = [...]
* import fastlid
* fastlid.set_languages = ['nl','fr'])
* TODO: Commandline interface

# support 176 languages
print(supported_langs, len(supported_langs))
# ['af', 'als', 'am', 'an', 'ar', 'arz', 'as', 'ast', 'av', 'az'] 176
fastlid("test this")
# ('en', 0.765)
fastlid("test this 测试一下", k=2)
# (['zh', 'en'], [0.663, 0.124])
fastlid.set_languages = ['fr', 'zh']
fastlid("test this 测试吧")
# ('zh', 0.01)
fastlid.set_languages = None
fastlid("test this 测试吧")
