feat: Brick (#1)

* feat: Brick

* feat(brick): add PowerBrick and update Brick, ExoplodeBrick, ProtectedBrick

* docs(brick): add Javadoc for Brick, ExoplodeBrick, PowerBrick, ProtectedBrick

* refactor(brick): remove NormalBrick and StrongBrick

* refactor(brick): rename packages and update formatting settings

- Renamed package from `com.github.codestorm.brick` to `com.github.codestorm.bounceverse.brick` for consistency.
