Code Review

This pull request introduces the new java-maps-navconnect module, which provides a Java idiomatic client for the Google Navigation Connect API. It includes the generated client library, stubs, protobuf classes, samples, and tests. Feedback on the changes suggests improving the repetitive description of Navigation Connect in the README.md to make it more informative for new users.
