feat: add data_scanned_in_bytes to adapter response

[jurgispods]

Description

This PR adds the field data_scanned_in_bytes to the adapter response, which allows for monitoring of Athena costs per DBT project/model/etc., see #335.

Models used to test - Optional

Tested by running some models from my own DBT project and comparing the output of

cat target/run_results.json |  jq '.results[].adapter_response.data_scanned_in_bytes'

with the query stats from Athena console -> results checked out.
