Was relying on the main plugin's subscribe-all behavior

Prevents data type issues where topic ordering is nondeterministic and type information could arrive after sources are set up

Was based on NT table structures, which weren't returning correct data

Shuffleboard historically relied on the assumption that a leading slash was optional for paths in networktables. NT4 changed that by making topic names exact (so two topic names only differing by the presence or absence of a leading slash would be two unique topics), which broke NT data sources for topics without leading slashes

We don't write to the metadata topics, it's all sent over from the server
