Previously, some methods of the AIS reader classes were package-private. By changing their visibility modifier to protected, subclasses in other packages can now override these methods for customization or extend their functionality. This increases the flexibility of the AIS library for diverse scenarios, while keeping encapsulation safe for the remaining codebase.

Removed unneeded debug logging of the `CommentBlockLine`

Change visibility of certain methods to protected
