Sim GUI can't display protobuf data

[Gold856]

Describe the bug When publishing protobuf data, like a Pose2d or Translation2d, Sim GUI will display the fields (like translation and rotation for Pose2d or x and y for Translation2d) but it won't display the actual data.

To Reproduce Steps to reproduce the behavior:

1. Use a ProtobufPublisher to publish an object like Pose2d.
2. Run the simulator.
3. Observe the lack of data, but the presence of the fields.

Expected behavior Sim GUI should display the data like Glass does.

Screenshots Glass showing data:
