Integration with icu4x?

[Boscop]

Btw, there is prior art in the form of i18next, fluent-rs and now icu4x: projectfluent/fluent-rs#329
It probably makes sense to integrate icu4x into leptos_i18n or take inspiration from it, regarding how it handles the intricacies of languages.

I've been looking for a way to handle localisation for date/number/ect... and icu4x looks like a good fit, I'll look into it and how to integrate the features it propose, thanks for the suggestion
