finchie/l10n_embed - Change JUV7C6ET4ZQJNLO7B4JB7XMLV2YUBZB4ARJHN4JEPHDGGBWGLEVAC

Create initial prototype of `fluent_embed_interaction`

This is an MVP for localizable prompts, which also supports interactive and non-interactive environments. Future work will most likely focus on enabling non-intrusive testing of code that uses these prompts, along with support for progress indicators.
