[Bug] - Fix some issues discovered while implementing latest version of this package into NextJS app

[jupiter007]

1)DefaultResearchOutputCustomColumn is not available to NextJS app. It needs to be added to the questions/index.ts file
2) These errors are breaking pages in NextJS app:

./dmptool-types/dist/dmp/index.js:7:30
Module not found: Can't resolve 'fs'
   5 | Object.defineProperty(exports, "__esModule", { value: true });
   6 | exports.ExtensionJSONSchema = exports.DMPToolExtensionSchema = exports.RDACommonStandardDMPJSONSchema = exports.RDA_COMMON_STANDARD_VERSION = void 0;
>  7 | const fs_1 = __importDefault(require("fs"));
     |                              ^
   8 | const path_1 = __importDefault(require("path"));
   9 | const zod_1 = require("zod");
  10 | const extension_1 = require("./extension");

In @dmptool/types src/dmp/index.ts the code imports fs and the const RDA_COMMON_STANDARD_JSON_FILE = resolverSchemaPath() runs immediately when anyone imports this file. In the browser, all top-level code from index.ts executes immediately, and it tries to call fs.existsSync, but fs is undefined in the browser.

3. selected was removed from options preventing a way for users to save default options when creating a question. It needs to be added back

4. Need to fix the QuestionDefaultMap because some of the mappings are incorrect (example: boolean is mapped to DefaultAffiliationSearchQuestion
