The `openssl`/`curl` command generator script in `rest_scripts` supports both unsigned streaming payload trailers and signed streaming requests. This update adds support for signed streaming requests with trailers (`STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER`).
**Usage**
The script generates an OpenSSL command file, which is then used to send the request.
Example:
```bash
go run tests/rest_scripts/generateCommand.go \
--awsAccessKeyId access \
--awsSecretAccessKey secret \
--client openssl \
--commandType putObject \
--bucketName test \
--payload "hello" \
--payloadType STREAMING-UNSIGNED-PAYLOAD-TRAILER \
--chunkSize 8192 \
--objectKey obj \
--filePath req.txt \
--checksumType crc64nvme
```
You can then send the request with:
```bash
openssl s_client -connect 127.0.0.1:7070 -ign_eof < req.txt > response.raw
```
