Checklist

• This is a suggestion for LiveTL, not Hyperchat. I will go to the Hyperchat repo to suggest a feature for Hyperchat.
• This is a suggestion for the LiveTL web extension, not LiveTL iOS or LiveTL Android. I will go to the iOS or Android repo to suggest features for those platforms.
• I have checked for a duplicate or similar feature request/issue. I made sure to check closed issues as well.
• I am not reporting a bug. If I am, I will use the bug report issue template.

Is your feature request related to a problem? Please describe.

We currently only have a limited set of languages that Users can select from.

Describe the solution you'd like

Use ISO 639-1 and ISO 639-2 to add support for a bunch of languages, as well as their language codes. (though we can prob ignore stuff like en-US, instead using just en)

Describe alternatives you've considered

To save you the couple hours to make the data all nice, just a heads up that the API repo has a list already done up. It's in SQL, but should be easy enough to bulk edit into the proper JSON format
