initial multilingual version

Easily extendable to many language using the add_culture_data script. This will do translation, gender consistent naming, suggest names, extend data, etc. So if anyone wants to run a language not committed in EVA data, it is trivially easy to do so.
Readme section showing basic of adding a language.

This adds:
Multilingual data schema and content (initial utterances, system prompt, name aliases)
multilingual support in code
Prompt updates to support multi languages
Script to "add a language" with high degree of automation
WER metric normalization rules, dynamically set per language and creatable via LLM through adding script
Automatic .env.example adjustments (maintains config app accuracy)

Still TODO:

• Currencies
• Phone numbers (airline only problem)
• Actually committing the translations (didn't want to burn credits until finalized)
• Analysis
• Testing a large variety of models to ensure they actually get the language code they expected (es-MX vs es, for example)

can you also add ensure_ascii=False to AuditLog save()

Also, since we have all these alias in each file, shouldn't we put all the aliases in a separate common file?

Definitely can do soon. Can publish first though (blog timing) since this is a nicety and less functional
