Allow unparsed binary data to be used for ingestion

[swallez]

PR #474 added a BinaryData class used to pre-serialize documents in bulk requests in order to evaluate their size.

This PR extends the usage of BinaryData to API requests whose body is an application-provided object. These are the create and index ingestion endpoints, in addition to bulk. This allows providing JSON data as a binary blob without incurring the cost of parsing and reserializing with no additional processing.

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub git fetch # Create a new working tree git worktree add .worktrees/backport-7.17 7.17 # Navigate to the new working tree cd .worktrees/backport-7.17 # Create a new branch git switch --create backport-508-to-7.17 # Cherry-pick the merged commit of this pull request and resolve the conflicts git cherry-pick --mainline 1 b96dca4c4f3a7701493f81dca9930843968f722d # Push it to GitHub git push --set-upstream origin backport-508-to-7.17 # Go back to the original working tree cd ../.. # Delete the working tree git worktree remove .worktrees/backport-7.17

Then, create a pull request where the base branch is 7.17 and the compare/head branch is backport-508-to-7.17.
