> 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.
