BUG - Objectify<...> is super slow

[TwoAbove]

Currently, we use Objectify<json object> to get typings for data like perks.json etc.

This works, but is super slow for development (intellisense lags because of this).

The proposal is to either craft typing declarations for jsons by hand, or look into something like app.quicktype.io, although preliminary results were lackluster.
