Subject: [PATCH] `README.md`: invoke lambda function with `raw-in-base64-out`

In AWS CLI v2, you need to set `cli-binary-format` to
`raw-in-base64-out` to send binary values as literals. You otherwise
need to pass base64-encoded data.

See https://docs.aws.amazon.com/sdkref/latest/guide/setting-global-cli_binary_format.html.
