Datastreamer Tool JSON Stream

[praetoriansentry]

What does this PR do?

This is a meant to be a backward compatible change to the data streamer tool to support outputting data in JSON format. By default this command still outputs colorful dot padded output:

go run main.go decode-batch --cfg config/tool.config.toml --batch 489

If we add the --json flag, the output should print each entry in a parsable json format

go run main.go decode-batch --cfg config/tool.config.toml --batch 489 --json

Would be helpful for leveraging this tool in integrations with other systems and processes.
