Retrieving object metadata requires downloading the object

[JonMerlevede]

Describe the bug
Querying S3 object metadata, such as an object's encryption key, requires downloading object contents.

Steampipe version (steampipe -v)
Steampipe v0.24.2

Plugin version (steampipe plugin list)
Example: v0.147.0

To reproduce
Execute a query such as select sse_kms_key_id from aws.aws_s3_object where bucket_name = 'yourbucket'.

Expected behavior
Steampipe retrieves only the object's metadata, not the object itself.

Additional context
The current code does use getS3ObjectAttributes for some limited metadata keys, but calls getObject for most.
