Bugzilla

In order to remove CLD2, we'll need to migrate to the new fastText language detector, which the translations infrastructure will rely upon. This will involve a download for the first time it is run, since we don't ship with the wasm blob or language models. This could cause a behavior change, or for the language detection to fail if the download fails. I'm going to block on Bug 1813161 now since this touches the language identification code.

Here is a [searchfox search](https://searchfox.org/mozilla-central/search?q=LanguageDetector.jsm&path=&case=false&regexp=false) of consumers.

* The extension API uses `browser.i18n.detectLanguage`.
* Reader mode uses it to detect the article language.

:zombie, :mixedpuppy As module owners of the web extensions, do you have any issues with me moving to use our new language detection library? It's using `fastText`, and should provide more accurate results. The trade off is that it requires a download upon the first use.

I'm not seeing code owners around a decision for Reader Mode, so I'll rely on my reviewer.

The downloads for fastText are a 875k wasm, and 938k language model.
