Get inspirations from Go Text

[brawer]

The golang x-text library has re-implemented most of ICU from scratch, and some of their algorithms and data structures might be interesting for the icu4x project (afaik x-text was not just a port of the ICU codebase to another language, but an actual re-implementation). You might want to have a look at their code, or talk to @mpvl who wrote most of it.

@brawer Are there specific areas of the code you think would be useful in particular?

Just looked over the code here. Some high-level takeaways:

• The library formats using what looks like a "localized Sprintf", which is a different model than the "create formatter then fall format function" that we see in ICU
• Data is generated into static files, similar to ICU4X Databake
• Some interesting design choices in e.g. the DisplayNames module that could serve as inspiration for ICU4X

I'll take this issue with the action to list this library as "prior art" in the contributors guide so that folks can reference it when designing new features.
