Stack agnostic

Inlang is a file format with no depedency on a tech stack. Hence, it can be used with any tech stack.

The only thing that is needed are import/export plugins for the translation file format that is used by the tech stack. For iOS for example, the XCode strings catalog can be used. For Flutter a .arb plugin would be the right choice.
