Replace dtslint with tsd to test .d.ts files (#1051)

This patch replaces `dtslint` with `tsd` for testing `.d.ts` files, ensuring improved type validation and updated test coverage, including:

1. Added a new test file, `index.test-d.ts`, with comprehensive type assertions using `tsd`.
2. Removed existing test file, `index.d.ts` , `index.d.ts`, `test.ts`, `tsconfig.json` and `tslint.json` that is no longer needed.
3. Removed `dtslint` from `dependencies` for `package.json`.
4. Added `tsd` and `@types/node` into `devDependencies` for `package.json`.

After this patch:
1. Running `npm test` will test for `.d.ts` files.
2. Running `npm install` will generate interfaces for `.d.ts` files.

Fix: #1050
