Description

When analyzing data related issues I found it really helpful to filter or portprocess the contents of parquet files on the command line using jq (https://stedolan.github.io/jq/manual/).

Currently the output of parquet-read is in a custom json-like format, I propose to add an optional flag that outputs the contents as json using the serde_json library. This should probably be behind a feature gate to avoid adding the dependency for everyone.
