finchie/l10n_embed - Change HCGVXOF7P3KKS2IMGVJWI2POVOZQFPXH26YVBJZRSOYSUM4CHUBQC

Add language negotiation using `fluent-langneg`

Notably changes the signature of LocaleCategory::get_locales from Option<String> to Vec<String>, as there could be multiple options and the first choice (what was returned before) might not be supported.
