Scripting in different languages (porting collections from MT4, PINE, etc...)

Continuation of this thread: #31

We could easily add an option to import prefabs (prefab is a ready-to-use version of navy: https://github.com/project-nv/night-vision/blob/main/src/core/navy/parserOv.js#L197). Basically, there is no problem of adding more languages that compile code into prefabs.

Right now this would only work for Overlays, coz Indicators are not using the same technique.
