Changes to Result

Changes to the Geode Settings API

static Result<std::shared_ptr<MyCustomSettingV3>> parse(std::string const&, std::string const&, matjson::Value const& json) {
   auto res = std::make_shared<MyCustomSettingV3>();
   auto root = checkJson(json, "MyCustomSettingV3");
   // ... some code here ...
   return root.ok(res);
}
// should now be:
//                            ↓ here
static Result<std::shared_ptr<SettingV3>> parse(std::string const&, std::string const&, matjson::Value const& json) {
   auto res = std::make_shared<MyCustomSettingV3>();
   auto root = checkJson(json, "MyCustomSettingV3");
   // ... some code here ...
   //             ↓ here
   return root.ok(std::static_pointer_cast<SettingV3>(res));
}

auto root = checkJson(json, "[file.json]")

// ... code
