Does CPP client support STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER request?

[blackcup]

STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER is mentioned in https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-auth-using-authorization-header.html, but I can not search it out in this repo.

for all S3 operations we use STREAMING-UNSIGNED-PAYLOAD-TRAILER (link). is there a specific reason you want to stream sign the trailer?

Thanks. No specific reason, just want to get familiar with the S3 ecosystem, reading source codes of s3 client is a good start. Thank you for your time.
