RecordsQuery returns `encodedData` if the data is under a certain threshold

Currently the implementation returns an optional property `encodedData` with `RecordsQuery` results if the dataSize is under a determined threshold.

This is to prevent users from having to issue `RecordsRead` for each record to retrieve the data if it is a small size. `RecordsRead` can still be used for large data within a result set in order to allow data streaming.
