Adds raw body information (body as buffer, encoding)
to `RequestDetails` to support more request validation
use cases.
Additionally, uses the raw body to retrieve the transmitted
JSON string unparsed/raw to correctly validate the signature.
Previously, we re-stringified the parsed JSON payload
which could lead to different JSON strings.
Those differences can lead to the rejection of requests
due to a mismatch in expected signature.
