Fixes and improvements
* Allow to use RS256/ES256 algorithms to sign JWT. [[Documentation](https://fastapi-users.github.io/fastapi-users/configuration/authentication/strategies/jwt/#rs256-example)] Thanks jtv8 🎉
* Allow to customize password hash strategy and algorithms [[Documentation](https://fastapi-users.github.io/fastapi-users/configuration/password-hash/)]
* ⚠️ For SQLAlchemy ([v3.0.0](https://github.com/fastapi-users/fastapi-users-db-sqlalchemy/releases/tag/v3.0.0)) and Tortoise ORM ([v2.0.0](https://github.com/fastapi-users/fastapi-users-db-tortoise/releases/tag/v2.0.0)), models have been updated so that the `password_hash` column can store longer strings. You'll likely need to perform a database migration.
