Can we add support for the

1. Reading JSON byteArray - Decode byte array in to root content
2. Default values - Support to provide default value for any given non-existing property
3. Object Processing along with JSON Array - Support to have filter & projection on a single JSON object along with the JSON Array

I can raise an MR having all these functionality
