(Unicode C) S3 Download Specific Version of File

Demonstrates how to download a file from the Amazon S3 service using the versionId query parameter.

Note: This example requires Chilkat v9.5.0.89 or later. (A problem regarding AwsSubResources w/ downloads was fixed shortly after the v9.5.0.88 release.)
