Back to javax for SpringBoot compatibility

Had to back out the port to the jakarta packaging as springboot is not compatible. Moved back to javax for all the JAXB annotations.

SSL initialization using system properties.

Fixed issue with initialization of SSL using system properties.

Ready for initial use.

This version can be used as a simple client for accessing an NSI-DDS server:

• Includes fixed SSL context handling.
• Includes simplified constructor parameter passing.
• Have not yet worked out how best to handle notifications so this release does not support this as an option.
