JSON logs appear in Sumo as strings

Description

When using the sumologic-lambda-extension to send lambda logs to SumoLogic originally JSON logs appear as strings in Sumo.

Log in CloudWatch:

Log in SumoLogic:

Steps to Reproduce

Use a JSON formatter to emit logs in JSON format I guess?

Expected Behavior

I'd expect the logs in Sumo to be properly parsed as JSON logs so that they can be expanded/collapsed/queried etc.

Relevant Logs / Console output

Your Environment

          SUMO_LOG_LEVEL: error
          SUMO_LOG_TYPES: function

Additional context

Also as a related sidenote/feature request: could we have an envvar switch to have the logs delivered to sumo without any additional information wrapping the actual log message? So no IsColdStart, LayerVersion etc. only the log message itself sent to Sumo?
