Base Issue: Syncing Features from `psnawp` to `psn-api`

This issue will serve as the base tracker for syncing and migrating missing features from [`isFakeAccount/psnawp`](https://github.com/isFakeAccount/psnawp) to [`achievements-app/psn-api`](https://github.com/achievements-app/psn-api).

The [`psnawp`](https://github.com/isFakeAccount/psnawp) repository by [@isFakeAccount](https://github.com/isFakeAccount) is undoubtedly the most complete and well-maintained PSN API library. The goal is to bring `psn-api` up to date by identifying and implementing these functionalities.

As the work progresses, related issues and pull requests will be linked here.
