Interpret BinaryArray as JSON

*Note*: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-10987

Create lightweight wrapper, `JSONArray` to interpret `BinaryArray` values as serialized JSON. Leverage recent work for inferring JSON schema to support conversion to `StructArray`.

Example:
{code:java}
let json_array: JSONArray = binary_array.into();
let struct_array: StructArray = json_array.try_into().unwrap();
{code}

Start by locating BinaryArray, StructArray, and the recent JSON schema inference work mentioned in the issue. Determine how a JSONArray wrapper should convert serialized JSON values into a StructArray; done means the proposed conversions work for the example and the inferred schema is supported.
