> This minor change makes newBuilder() public to reduce verbosity for 
> downstream.
> To give you example, I am working on a parquet read / write into Arrow Record 
> batch where the parquet data types are mapped to Arrow data types.
> My Repo: [https://github.com/mindhash/arrow-parquet-go]
> In such cases, it will be nice to have a builder API (newBuilder) be generic 
> to accept a data type and return a respective array. 
> I am looking at a similar situation for JSON reader. I think this change will 
> make the builder API much easier for upstream as well as internal packages.
