Fix --json with new format (#409)

Fix output with `--json` not being displayed after using new aggregated collection.

Fixes #408

Add S3 Express Append benchmark (#405)

Each thread uploads one object and appends to it.

upgrade all deps

Add optional checksums (#400)

Usage is similar to [mc](minio/mc#5043).

> To add a [checksum](https://docs.aws.amazon.com/AmazonS3/latest/userguide/checking-object-integrity.html) to the uploaded objects, use `--checksum` parameter.
The following checksums are supported: `CRC32` (composite), `CRC32-FO` (full object), `CRC32C`, `CRC32-FO`, `CRC32C`, `SHA1`, `SHA256` and `CRC64NVME`.
Adding a checksum will always disable MD5 checksums.

update dep one more time

Add aggregated format compare (#389)
